3PRACTICE PROBLEM
A diffraction grating is used with a laser that emits light with a monochromatic wavelength of 632.8 nm. The grating has 555 grooves/mm. The laser light is incident at an angle of 35° and diffracted by the grating at an angle of θ. Determine the angles θm at which the primary maxima of the diffraction pattern will be observed.
