Given the visible light spectrum above, which of the following would not be observed from sunlight entering and then exiting a crystal prism?

Infrared light
Blue light
Green light
Yellow light

1 answer

When sunlight enters and exits a crystal prism, it undergoes refraction and dispersion, separating into its constituent colors of the visible spectrum. This typically includes colors such as red, orange, yellow, green, blue, and violet.

However, infrared light is not part of the visible spectrum; it falls outside the range of visible light that can be seen by the human eye. Since a prism is designed to split visible light, infrared light would not be observed exiting the prism as part of the visible spectrum.

Therefore, the correct answer is Infrared light.
