Look at the picture of the prism separating light. Which explains why a prism can separate sunlight into a rainbow of all the visible colors? Right triangle prism with beam of white light touching its right corner and beam of colored light coming out from its base Question 4 options:
A. Light of each wavelength travels at a different speed through a vacuum.
B. The glass of a prism absorbs some colors and transmits others.
C. Light of each wavelength is refracted at a different angle.
D. The prism reflects light of each wavelength at a different angle.
It’s D. First of prisms are used to break up light conduit spectral colors because of the refractive index depends on frequency, the white light enters the prism and is a mixture of different frequencies each of which it’s been slightly differently.
