The index of refraction for violet light in silica flint glass is 1.66 and that for red light is 1.62. What is the angular dispersion of visible light passing through an equilateral prism of apex angle 60.0∘ if the angle of incidence is 45.0∘? (See figure. The index of refraction for air is 1.00.)

$Assume that two waves of light in air, of wavelength 480. nm, are initially π rad out of phase. One travels through a glass layer of index of refraction n1 = 1.45 and thickness L. The other travels through an equally thick plastic layer of index of refraction n2 = 1.65. What is the smallest value of L so that the waves end up exactly in phase once they pass through the two media? 1.20 × 103 nm 300 nm 480 nm 1.80 × 103 nm 960 nm$

$A glass cover is placed over a water drop on a glass slide. When this is done, orange light (λ = 605 nm in air) is reflected particularly strongly. What is the minimum possible thickness (nm) of water between the cover and slide? The index of refraction of the glass (cover and slide) is 1.54 and is 1.33 for water. The slide is too thick to be a thin film, just consider the water sandwiched between the cover and slide to be the film. 199 227 398 151 369 114 455 512 302 284$

$A horizontal, parallel-sided plate of glass having a refractive index of 1.47 is in contact with the surface of water in a tank. A ray coming from above in air makes an angle of incidence of 38.0∘ with the normal to the top surface of the glass. Part A What angle does the ray refracted into the water make with the normal to the surface? Use 1.33 for the index of refraction of water. Express your answer in radians. θ = radians$
