Is the pupil of your eye an emitter of radiant energy or an absorber of radiant energy?
The pupil does not absorb anything, it transmits light energy to the retina at the back of they eye, the retina does the absorbing. It certainly does not emit anything either, though aliens in scifi films can have glowing eyes! Some animals like cats have reflective eyes, but they are not emitting light, only reflecting incident light.
Light reaches areas that are not in direct light by means of?
Light reaches areas that are not in direct light by means of indirect light. The indirect light reaches the areas by reflecting off other surfaces.
What visual mechanism might explain red eye?
Often, people who take pictures will notice that their photos come out with people having bright red eyes. This is caused by the flash of a camera actually seeing the light reflecting off a person's retina.
What is meant by luminous?
Giving off light, as a light source. The sun, a light bulb, and a candle are all luminous. The moon is not because it does not give off its own light but reflects it from the sun; it is illuminated.
The inside of both camera and the eye is colored black. explain the advandage of this?
Since black absorbs light instead of reflecting it, the black finish inside of you camera stops stray light from affecting the image formed on the film or digital sensor. This stray light includes light that strikes the lens at an angle where it is not part of the image AND the light that may be reflected off of the film or sensor. The same really occurs with the inside of the eye. The sharpest image will always be produced when stray light is properly controlled.

Why Do you see objects when light from them is reflected into your eyes?
Our eyes are specifically designed to detect light. The objects reflecting the light change the property of light, including its intensity and color; this allows us to make conclusions about the objects it was reflected from.Our eyes are specifically designed to detect light.

Does a reflecting telescope gather light with a lens?
No, with mirrors; but there are lenses in the ocular that do gather the light from the mirror and make an image you can see with your eyes.
What is the difference between giving off light and reflecting light?
Giving off is emitting it and reflecting light is reflecting it
Is a star a source of light energy?
Yes. It is a source of light and heat energy. Anything neither giving out light nor reflecting it will be impossible to see by our eyes.
Because you see plants as looking green this means plants are absorbing all other colors of light and reflecting the light to your eyes?
yes
What type of lens does a reflecting telescope use?
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
