A light beam of wavelength 550 nm is incident on a sheet of glass of index of refraction 1.3. Surrounding the glass is air (index of refraction about 1.0). If no reflected light is observed, what can one conclude is the thinnest the sheet of glass can be?
Please explain the answer.

A beam of coherent light of wavelength A0 623 nm in air is incident on a rectangular block of glass with index of refraction n 1.40. If, after emerging from the block, the wave that travels through the glass interfers destructively with the wave that travels through air. We ignore reflection on the block faces. Coherent...

62. A certain kind of glass has an index of refraction of 1.65 for blue light of wavelength 430 nm and an index of 1.615 for red light of wavelength 680 nm. If a beam containing these two colors is incident at an angle of 30° on a piece of this glass, what is the angle between the two beams inside the glass?
