Does a prism separate light into only the visible spectrum or the entire spectrum?
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of visible light.
Can light travel through matter?
Yes! Light travels through any material that does not completely absorb it. Visible light can only travel through materials that are called either transparent or translucent. Visible light travels through glass all the time. Visible light also travels through your cornea and the gel-like material that is in your eyeball. There are other types of light than visible light, such as ultraviolet (UV). UV is light that has more energy than visible light. This is the type of light that can give you a sunburn. There are even more energetic types of light like X-rays. They go through lots of material that visible light can't -- like skin and organs, but they do not go through bones or teeth very well.
Is light visible or invisible and why?
Light is both Visible, and Invisible. It depends on what frequency of light it is, and also what Species you are. For example, we Humans can't see ultra violet light but some animals, like Snakes, can see it.
Would it be easier to resolve nearby objects if you detected them using ultraviolet radiation rather than visible light?
It is actually true that the shorter wavelength of UV would give you finer resolution - although for most purposes, visible light works perfectly well.
Are infrared radiations emitted by glowing of firewood?
Yes - infrared radiation is heat. Glowing firewood emits heat (as well as visible light)

Which electromagnetic waves are produced by the sun?
Visible light because some of the energy that reaches the earth from the sun is visible light. The visible light from the sun is white light. White light is visible light of all wavelengths combined. Light from lamps in your home as well as from the fluorescent bulbs in your school is also white light.
Which regions of the visible spectrum in which chlorophyll absorbed light very well?
Chlorophyll absorbs purple/blue light really well and orange/red light too. It doesnt absorb green light very well and refects most of ot, making plants appear green to us. Chlorophyll absorbs best in the 600-750 nm (nanometer) range
Which region of the visible spectrum is not absorbed well by the chloroplast?
green light
Does electromagnetic spectrum only include visible light?
No, it includes alpha, beta, gamma, x-rays and ultraviolet rays also. In other words it includes the visible as well as non-visible light spectrum.
Is visible light a type of ultraviolet radiation?
No, it is a type of electromagnetic radiation, which ultraviolet is part of as well.
How light reflects from aluminum foil?
Visible light refelects very well from metallic aluminum. (See the link for more details on the physics of light reflections)
What is an everyday example showing how heat is absorbed from visible radiation and transferred to infrared radiation?
Infrared Radiation is at a Frequency that is outside of the range of the Visible Spectrum. Visible light does not 'become' Infrared Light. If a light source is giving off energy in the form of HEAT it is emitting Infrared Energy, as well as Visible Light. A light source can also "Heat" matter by giving off energy such as X-Rays, or Gamma Rays, or more commonly MICROWAVE Radiation.

What type of rays can you make and how?
Well, a flashlight omits ultraviolet rays. A microwave omits microwave ray and visible light with any source of light
Why use microwaves instead of visible light?
-- We have no technology that can generate visible light at power levels that are easy to generate in the microwave. -- Visible light won't warm up a leftover chunk of meatloaf. -- For telecom applications, microwaves sail right on through atmospheric conditions that scatter, diffuse, and absorb visible light. But your question doesn't mention what uses you're thinking of, and visible light certainly has its place. For example, microwave traffic lights at intersections would not work out too well. Neither would a microwave chandelier hanging over your dining-room table.
What extra information can be gained by using infra-red as well as visible light?
