Question 34 • FL-2003310-Physical Science B-CR (Exam Only)

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

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

Explanation

First, light strikes the grating’s grooves. The grooves diffract the light, sending different wavelengths in different directions; those separated wavelengths then reach the eyes, where they are perceived as different colors. Therefore, the correct sequence is “light strikes the grooves → different wavelengths of light bend at different angles → diffracted wavelengths reach the eyes → the eyes see different colors,” choice D.
