Question:
how come light reflected off an object is not the same as light from a light source?

Since colored objects are basically reflecting a specific frequency of light and absorbing all other frequencies, why doesn't a colored object act like a source of monochromatic light (when light is incident on it), the same way a light source going through a filter would?
Three answers:
like this or like that

I am not sure if this will help but at science class, we had a prism light reflected into prism as a single beam come out one side as the spectrum rainbow colours...refraction in suns rays through water (raindrops) can be seen as rainbow. Rainbows from the air from a plane at high level are seen as a circle, normally seen as part of the rainbow at ground level. Mike 1948 answer is interesting.

scince studying the light from stars note that the colours are made up of unusual proportions.

When analysed through a spectroscope (basically a prism) the rays of some stars contain a distinct band of yellow light. It is known that glowing sodium also has this characteristic and thereforestars are made up parrtly of that element...

It does. But since almost all colored objects produce a diffuse reflection (all spread out) it can be very hard to see. If you take a dark room and a tightly focused white light beam which is aimed at table top or white paper on a flat surface and in the line of reflection tape a piece of white paper to the wall, if you lay colored paper on the table, the white wall will be colored. But not very brightly.

This effect has to be considered by interior designers in choosing wall colors, by set designers for theater, and by clothing designers in picking colors. All of these have to deal with what happens when white light bounces off of colored surfaces. A light skinned pinkish person wearing certain shades of green shirts/blouses can look ghastly in the reflected light.

maximum are organic understood phenomenon, like airborne dirt and mud, sparkle, reflections, etc. it is impossible to tell without seeing the photograph, or perhaps then an answer is iffy. right here some issues to study: a million. colour. maximum are white with a blurry seem. yet whilst it has blue and green rainbow or prism streaks then it is maximum in all danger led to by using a lens interior the digicam, or a mirror interior the digicam, or the lensing effect of moisture. 2. Consistency of center of orb. this would be an excellent tell right here. If the orb is led to by using a speck of airborne dirt and mud on the lens it extremely is going to likely be around, yet will seem much less white interior the middle. it extremely is going to look like the detrimental of a purple blood cellular. This ringing effect is led to via fact the speck of airborne dirt and mud is out of concentration, for this reason appearing plenty larger than it is. 3. Foreground or history. ninety 5 p.c. of all orbs are interior the foreground via fact they do no longer look to be paranormal in any way. history orbs are the super value ticket products. those are orbs that seem at the back of another merchandise and are in part obscured. it is, if the orb have been at the back of your hand, and your hand completely blocked component to the orb, then you could in all danger have a genuine deal paranormal orb. the explanation such an orb is so significant is that one in all those placement interior the scene removes concerns concerning the digicam lens. 4. area of orbs. i understand you in basic terms have 2 orbs, yet once you had many, then it could be significant to be conscious the place those orbs have been placed from scene to scene. If there's a trend, like they are in basic terms over dark aspects, or in basic terms on mild aspects, or in basic terms on the sides, etc, then it is for effective no longer a mystical orb. i'm hoping this suggestions helps.
