Monochromatic light of wavelength 500 nm is incident normally on a diffraction grating.If the third-order maximum of the diffraction pattern is observed at 32.0°,what is the total number of maxima can be seen?

Question

Quizplus · Accepted Answer

The total number of maxima is given by (m+1), where m is the order of the maximum. In this case, the third-order maximum is observed, so the total number of maxima is (3+1) = 4.
