Increasing the wavelengths in a double-slit experiment has what effect on the position of maxima on a screen at fixed distance?
A) none
B) maxima get closer together
C) maxima get farther apart
D) maxima get cancelled by minima
E) maxima pass minima on the screen

Question

Quizplus · Accepted Answer

The position of the maxima on the screen is directly related to the wavelength of the light used in the double-slit experiment. The larger the wavelength, the more the diffraction occurs and the larger the distance between maxima on the screen. Therefore, as the wavelength increases, the maxima get farther apart.
