1 answer

Here are the answers to your questions:

  1. Question 1: When white light passes through a prism, the light C. separates into a rainbow.

  2. Question 2: When light of a certain color with the right amount of energy is shined on an atom, an electron inside the atom C. jumps from a lower energy level to a higher energy level.

  3. Question 3: When this happens, certain lines (colors) of light are missing. This is called a/an D. absorption spectrum.
