The Diffraction Grating

The Diffraction Grating problem 4

A deflection grid has a grating constant of . On a screen 1 m away, the first-order maximum image is produced at a height of 0.15 m.

  • What is the frequency of the incident light?

  • What should be the grating constant for the height of the maximum to be doubled?
