select all the correct answers.
which two possible explanations does the video give for why white light changes into colored light?
color is an impurity added to white light by the prism.
color is present in the materials on which white light shines.
white light contains seven colors, which are separated by the prism.
white light reacts with chemicals in the air to produce seven colors.

Explanation:

White light is a combination of seven - color spectrum (violet, indigo, blue, green, yellow, orange, red). A prism can separate these colors due to the phenomenon of refraction as different colors have different wavelengths and thus refract at different angles. Color is not an impurity added by the prism, nor is it due to a reaction with chemicals in the air in the context of a prism separating white light. And the color separation by a prism is not related to the materials on which the light shines.

Answer:

C. White light contains seven colors, which are separated by the prism.
