Increasing the wavelength in a double-slit experiment has what effect on the position of the 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 a screen at fixed distance is directly proportional to the wavelength of the light. As the wavelength increases, the distance between the maxima also increases. Therefore, the correct answer is C- maxima get farther apart.
