1. When it's absorbed into a medium, it will affect how things look. It limits the light available to be reflected or transmitted.

2. There's a thing that is called a light filter that is transparent to some kinds of light but is opaque to others. Sunglasses use these material to block out sunlight.

3. A black T-shirt will be a black T-shirt after it is painted, by any colors.

1. If EM waves are absorbed by the medium, they would disapear, and it will affect how things look, because it limits the light available to be reflected or transmitted.

2. Sunglasses are like light filter. It is transparent to some kinds of light and opaque to others. If the sunglasses are in a certain color, the sunglasses will reflect only reflect that color and absorb others.

3. The black T-shirt will always be black even when you mix a large amount of others. Black is the mixture of cyan, yellow, and magenta. Green is the mixture of yellow and cyan. But we cannot subtract magenta from the black T-shirt, so we cannot make a green T-shirt.

1. Absorption would occur, which is the disappearance of an EM wave into the medium. This limits the light available to be reflected or transmitted, thus causing the object to look different.

2. Sunglasses are a type of light filter, which is a material that is transparent to some kinds of light and opaque to others. For example, if the colored covers on sunglasses are red, everything will seem to be red because the other colored lights will be reflected.

3. It is not possible because black is the result of mixing the pigments cyan, yellow, and magenta. Since we cannot subtract one of these pigments from the black T-shirt, we cannot change it into a green one.

A1. We call the disappearance of an EM wave into the medium, the absorption. Absorption limits the light which are available to e reflected or transmitted. So when EM wave is absorbed into a medium, it will disappear.

A2. Well, I'mnot sure about this but I think that the sunglasses work because of it is mostly made of translucent materials. When you see through sunglasses, you can see but not that clearly like when you see trough just glasses, because sunglasses's . So I think that the sunglasses use translucent materials so the person who wears the sunglasses could see but not that clearly so he or she can't see the sun clearly.

A3. Cyan and magenta are called primary pigments which are the materials that can be used to produce colors. When the three primary pigments are mixed together in equal amounts, its result is black. Black reflects all the colors so unless you can suck the primary pigements of black, it can't produce green, which is the secondary color, I think.

1. When EM wave is absorbed into a medium EM wave disappears. Absorbtion of EM wave affects how things look because it limits the light available to reflect or transmit.

2. Features vary when the color of light changes. Light with black reflects every light that it passes. Which makes sunglass black and it protects our eyes from the sunlight by reflecting it.

3. We cannot makea green one becuase black T-shirt reflects all of light and the color doesn't changes no matter what color of light we use.
