What is the maximum number of lines per centimeter for which the m-5 principal maximum will be visible? (No units are necessary in your answer. 112.4 1/8 Previous Tries Post Discussion

Explanation / Answer

diffraction grating

dsin(theta) = m*wavelength

for max. sin(theta) = 1

=> d = m*wavelength = 5*562*10^-9 = 2810*10^-9

no. of lines/cm = 0.01/d = 3.558*10^3 = 3558
