Rainbow and Light Quiz

What causes the different components of a rainbow to be visible when white light passes through a glass prism?

• The white light gets absorbed by the prism.

• Each component of color travels at a different speed in a medium.

• The prism adds colors to the white light.

• The white light is reflected off the surface of the prism.

Which color in white light is refracted the least when passing through a prism, and why?

• Blue, because it has the shortest wavelength.

• Violet, because it has the lowest speed.

• Red, because it has the highest speed.

• Green, because it is in the middle of the spectrum.

What happens to violet light when it passes through a glass prism, and why?

• It is absorbed by the prism.

• It is reflected back.

• It is refracted the least.

• It is refracted the most.

What is the term used to describe the separation of white light into its component colors by a prism?

• Diffusion

• Dispersion

• Reflection

• Refraction
