Why do things need light?
For living things, light is one source of heat.For non living things, so that you would be able to see it if it's dark.
You are able to see objects around us because of what?
The light from its source is reflected by the objects into our eyes. Light travels in a straight line; therefore, when its path is blocked, it will change directions.
Are humans able to see the light?
Humans are able to see light (hence called "visible light" on the electromagnetic spectrum). Otherwise, you couldn't see anything. (And I have a B in science class...PLEASE)
Is leaf a non reflector of light?
i think it is a reflector of light as we are able to see a leaf in the presence of light, it means when light bounces back into our eye, we can see it otherwise we would not be able to see it. however it is not a good reflector of light, but a poor reflector of light.
Why can't you see anything without a light source?

What enables someone to see objects?
You need a light source for you to see a object. Without a light source, you wont be able to see anything at all. For example, it is a sunny day and you are sitting underneath a tree in a park reading a book. For you to be able to see your book, there has to be a light source. The only source of light that has the biggest possibility is the sun. The light from the sun travels in a straight line to the book you are reading which then reflects in a straight line into your eyes. The same concept is applied even if you are indoors but instead the light source can be the light bulb or maybe even the light from the sun coming in through the windows. It depends, but a light source is needed for you to be able to see anything.
What are the uses of a desk lamp?

Do real diamonds sparkle in the dark?
In a cave with zero light, you would not be able to see any reflection from a diamond since there is no light source. However, if there is moonlight, starlight, ambient light from any source, your diamond will sparkle.
What path does light take when to see an object?
When your eyes can detect images, light from a light source(s) is being reflected from the objects you see directly to your retina. For example, you are in a closed room with one overhead light fixture. The light from the light bulb is being filtered and scattered to light up some surfaces in the room. Light travels in a straight line. The shadow below a desk is where there is no direct light (no direct path to the light source). However, light scattered off the wall or chair will still reach below the desk, where you can still see a faded image. When you can see an image, bright or faded, it means that some light has reflected off that surface to reach your eyes. A bright image is seen when more light reaches that surface and reflects to your eyes than a fuzzy image. =========================

No. In order to see a rainbow in front of you, there must be a source of light behind you, and the rainbow you see will only have the colors of the source in it.
Why we cannot see the light source when using 3 opaque materials?
We cannot see a light source even if 1 opaque material is blocking the light source. Opaque materials do not allow light to pass through them so we cannot see light through them but we can still see light reflected by them.
