Question
A diffraction grating consists of many narrow slits separated by a constant spacing d. A beam of light with
constant frequency is shined onto the diffraction grating and the transmitted light is projected onto a distant
screen. Which of the following is true about the pattern of light that appears on the screen? Select all correct
answers.
The spot directly in front of the screen (
0 = 0
) is always bright, regardless of the light frequency.
The spot directly in front of the screen (
0 = 0
|3D
) is always dark, regardless of the light frequency.
O If the frequency of the light is increased, the spacing between the intensity maxima (bright dots on the screen)
increases.
If the spacing d is increased, the spacing between the intensity maxima (bright dots on the screen) decreases.
