Light with wavelengths of 520 nm and 630nm passes through a diffraction grating that contains 6000 lines/cm.
1) Calcualte the angles for the first and second order maxima that would appear on the screen
sin(Theta)m = m(Lamda)/d
The Attempt at a Solution
[6000 lines/cm]^-1 = 1.667x10-4 cm/line = 1.667x10-6 m/line
-light 1- m=1
Theta 1 = 22.2 degrees
Am I on the right track? I just have to for the other 3 situations?
