Solving a problem in physics section 2 point 37 optics

37. In the thick plane-parallel glass plate with a refractive index n1 = 1,5, covered with very thin film of uniform thickness h with a refractive index n2 = 1,4, is normally incident parallel beam of monochromatic light with a wavelength λ = 0,6mkm. The reflected light is the most weakened by interference. To determine the film thickness h.
