Question 13 • Physics in the Universe

Which lists the correct steps that occur when using a diffraction grating to bend light?

Answer
A
light strikes the grooves right arrow different wavelengths of light bend at different angles right arrow diffracted wavelengths reach the eyes right arrow the eyes see different colors
B
different wavelengths of light bend at different angles right arrow light strikes the grooves right arrow diffracted wavelengths reach the eyes right arrow the eyes see different colors
C
diffracted wavelengths reach the eyes right arrow the eyes see different colors right arrow light strikes the grooves right arrow different wavelengths of light bend at different angles
D
diffracted wavelengths reach the eyes right arrow different wavelengths of light bend at different angles right arrow the eyes see different colors right arrow light strikes the grooves

Explanation

First, light strikes the diffraction grating’s grooves. The grating bends different wavelengths at different angles, separating the colors; those diffracted wavelengths then reach the eyes, which perceive different colors. This sequence matches “light strikes the grooves → different wavelengths bend at different angles → diffracted wavelengths reach the eyes → the eyes see different colors.”
