A common use of a diffraction grating is to
A) split light into different polarizations.
B) focus light onto the retina.
C) separate light into its separate wavelengths.
D) reflect light into a different direction.

Question

Quizplus · Accepted Answer

A diffraction grating is designed to diffract light into its separate colors or wavelengths by creating a series of closely spaced parallel slits or lines on a reflective or translucent surface. The different wavelengths of light interfere constructively or destructively, creating a spectrum of colors that can be observed and analyzed. Therefore, choice C is the correct answer.
