A flat sheet of crown glass has a thickness of 2.6 cm. It is on top of a flat sheet of crystalline quartz that has a thickness of 3.2 cm. Light strikes the crown glass perpendicularly and travels through it and then through the crystalline quartz. In the time it takes the light to travel through the two sheets, how far would it have traveled in a vacuum

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
