Problem 40155.

Light with a wavelength of λ=0.7 µm is normally incident on a diffraction grating with a period of d=2 µm. Determine the angle φ of deflection of the rays corresponding to the maximum of the highest order. How will the angle φ change if the space between the grate and the screen is filled with water (n=1.3)?
