why does a beam of light, passing through a color glass (red lets say) changes its color?

Question

what I'm actually looking for is that what happens to the light beam, (or the particles of light), when passing through a colored glass?

Answer 1

White light is made of hte color spectrum,
all the colors combined.
A red plate of glass is red because hte material absorbs all the colors of light except for red, which is reflected back. Same reason light passing through turns red.

Answer 2

The color in the glass, a chemical compund, has properties that makes it absorb light. White light contains all colors. If the glass is red then that means it absorbs all wavelenghts in the light excepts, say, red. Only the red photons can go through. So you can say the glass is opaque to ever color except red. The absorbed photons makes the glass slightly warmer.

Answer 3

The colored glass looks colored because it absorbs some wave lengths of light and allows others (of that color) to pass through. White light consists of colors of all wave lengths and when some are selectively absorbed, we get color.

Answer 4

The filter absorbs radiation at particular wavelengths, and the light you see is whatever is left. The specific wavelengths absorbed depend on the electron structure of the compounds in the filter.

Answer 5

"Purple" is wrong, and blue light will not pass through red glass. The red glass will absorb the blue light, therefore no light will be transmitted. You could call that "black", since black is the absence of all light.
