You want to design a fluorite film (n=1.44) as an anti-reflection coat for glass (n=1.62). The diagram shows your eye looking down on the fluorite and glass, along with a light ray incident on the fluorite film.
a. Show a schematic of all reflected and transmitted rays needed until two rays reach your eyes. For each ray, discuss whether it has a reflection phase-flip relative to the incident ray.
b. Suppose the incident light is red (wavelength of 660 nm). Find the minimum non-zero thickness of fluorite so that no red light reflects into your eye.
a laser having an internal loss per round-trip of 0.015 when pumped at three times threshold has an output power of 4w.
An aluminium wire, of length l1 = 60.0 cm, cross-sectional area 1.00 x 10^-2 cm^2, and density 2.60 g/cm^3, is joined to a steel wire, of density 7.80 g/cm^3 and the same cross-sectional area. The compound wire, loaded with a block of mass in = 10.0 ..
