Can you create an illusion of the results of a detection spell? Like if you knew the opponent was going to cast detect magic, could you use Silent Image (or any illusion spell) to create what looked like a magical Aura?
Obviously, if they weren't casting the detection spell, this would be a dead give-away, but mostly wondering if it can be done within the rules as written.
Maybe there is a particular illusion spell you could use which would fool some detection spells.
But silent image specifically wouldn't do it.
You would need an illusion spell that mentions doing it. I believe there are some that do mention something to this effect, but I can't recall their names.

So is there no visual component to a detection spell?
Maybe I didn't clarify, the goal isn't to fool the dection spell, the goal is to fool the caster of the detection spell. Idea is to make the caster see an additional aura when they attempt to detect.
The spell you want is called magic aura.
Regular illusion spells are going to effect visible light, not the 'aura' of an object.

There is no indication of what is detected when someone uses a detection spell. But if nothing else, the will be able to identify that it's an illusion spell by the use of knowledge arcana or spellcraft.
The magic aura spell that Dave Justus mentioned it the best way to make an item detect as something else. Obviously making something detect as magical is the easy part, but if you used the spell to make a chair detect as an +2 unholy longsword then not only would detect magic reveal it, but a detect evil spell will as well, since an unholy weapon is evil-aligned. Obviously, if they get a chance to examine it closely enough to identify it as a +2 unholy longsword that would probably raise a red flag... since it isn't masterwork. Err... and it's obviously not a longsword.
Another option is using misdirection, assuming you have another object within range that actually is or detects as the state or property you wish. For instance, if you cast misdirection on a toilet, and targeted an actual secret door somewhere else in range, detect secret doors would identify the toilet as a secret door. Same thing with traps, magic, etc. Obviously, if you link a wall with a target that's invisible, see invisibilty (assuming you count that as being a detection spell fooled by misdirection) would reveal the target as being invisible even though it isn't, which would be puzzling.
As for using a silent image it would work if you knew specifically that a detection effect created a visible or noticeable aura or effect. For instance, if you knew that a creature using detect sombrero caused all sombreros to glow with a red aura, then you could use a silent image to give a red aura to any object you wish and it would appear to be triggering off the spell, which might fool anyone using the spell for a time (depending on how confused they would be by a fedora detecting as a sombrero) but it would also actually be glowing red for everyone, even those without detection spells.

Yeah, that's what I'm asking about. Nothing game breaking, doubtfully effective, just wondering if it can be done.
It most certainly can be done, yes, but again, the detection type spell would have to give off a visible aura, glow, or effect, most do not. They typically let the caster 'sense' the location or strength of an aura, but it isn't visible. I looked through most of the detect spells in the 2d20pfsrd and almost all of them are just a 'sense' type of thing, which you can't really duplicate.
While there's likely a bunch more spells in existence, I did find one detection spell that actually does give a visible effect in relation to strength to the caster:
Detect Rediation
That spell does give off a visible green shimmer and it is brighter the stronger the radiation is. So there is at least one spell, which you could use a silent image to duplicate, making an object seem to be glowing with radiation.
However, as a GM I would likely require you to have actually used the detect radiation spell (and seen a radioactive object of the strength you're trying to emulate) in order for you to get the actual strength, color, and glow correct. Again though, if someone is using detect radiation when they encounter your illusion it actually may fool them (especially since there is no additional concentration to determine extra info, unlike most detect spells), the object will actually be glowing for everybody to see, so your mileage will largely depend on who's looking at it. It still might fool them, depending on what they know about radiation, though objects have to be pretty irradiated to be glowing in most cases.

yes detect magic let you see magical aura and any spell or magical object has an aura
''You detect magical auras. The amount of information revealed depends on how long you study a particular area or subject.
1st Round: Presence or absence of magical auras.
2nd Round: Number of different magical auras and the power of the most potent aura.
3rd Round: The strength and location of each aura. If the items or creatures bearing the auras are in line of sight, you can make Knowledge (arcana) skill checks to determine the school of magic involved in each. (Make one check per aura: DC 15 + spell level, or 15 + 1/2 caster level for a nonspell effect.) If the aura emanates from a magic item, you can attempt to identify its properties (see Spellcraft).
Functioning spell (spell level) 3rd or lower faint aura, 4th-6th moderate, 7th-9th strong, 10th+ (deity-level) overwhelming
Magic item (caster level) 5th or lower faint, 6th-11th moderate, 12th-20th strong, 21st+ (artifact) overwhelming''
so yes it has an aura and you can detect it, and detect radiation only let you detect radiation in the surrounding area, and the radioactive auras is seen as a glowing green shimmer.
radiation do not equal a magical aura

John Murdock wrote: yes detect magic let you see magical aura and any spell or magical object has an aura I see nothing in detect magic, or almost any of the other detect [x] spells, that indicates a visible aura or glow or anything else, John Murdock.
I see that you 'detect' the auras, some spells let you 'sense' the aura, and you can locate the aura, and if the object giving of the aura is visible you can get more information. There is nothing in the spell that indicates more than a sensation or awareness of the power-level of the aura in the area. For instance, using detect magic in an area where there is a creature with invisibility cast on it would let you sense a magic aura in that area. You wouldn't see a glow, you would just sense it. Continuing to concentrate, you could sense that there were one (or more) magical auras and the strength of the strongest (likely faint). Assuming the invisible creature didn't leave the area you were concentrating on, you could detect/sense/feel what square it was standing in, but nowhere does it indicate you see a glow or any affect outlining it. The description is almost always that you 'sense' the aura, or creature, or effect that you are detecting for, except for detect radiation which explicitly states that it allows the caster to see a glow, the strength of which is determined by the radioactivity.
For instance, I don't think there is anything stopping a blind caster from using detect magic and scanning an area and getting a sensation from a magical object or spell. Even though they also could not 'see' a magic sword sitting on a table, they would have 'line-of-sight' to it, and thus could also attempt to gather more information as per the spell. There's no actual visible glow or data to be seen or read, it's a sensation of the power from the aura, which they can try and interpret or identify based on their spellcraft and experience. Now, if in your game it works differently and there is a visible illumination, that's okay, and others might do it that way, but I don't believe that's typical or intended. How does this affect a blind caster using detect radiation? Likely they still sense it around them, but also it's likely they can see a glow despite being blind to the rest of the surroundings (the glow specifically doesn't allow sight or otherwise illuminate an area enough to see, so it wouldn't really be giving them any actual vision either way, so nothing's really lost or gained. They would just be able to detect the radiation.)
Again, you could use an illusion spell to make a sword glow or flame like a torch, and that's certainly a power attributed to many magical weapons or objects (or anything with a continual flame), but that isn't the same as trying to emulate the 'sensation' of someone using detect magic and supposedly 'feeling' a 5th-level ongoing spell effect in the area.
