Question

A beam of light is incident upon a material whose dispersion coefficient is dn/dλ =-10.7 10-5 nm-1, with no = 1.500 when λο = 527.0 nm. If θ denotes the refraction angle, what is the absolute value of the angular separation Δθ of the refracted beams produced by this material if the incident beam contains wavelengths between = 467.0 nm and 2617.0 nm and the beam's angle of incidence i is 25.95*? A beam of initially unpolarized light passes through a sequence of three ideal polarizers. The angle between the axes of the first and second polarizers, labeled фіг , is 17.1° and the angle between the axes of the second and third polarizers, labeled ф23 , is 55.1.What is the ratio of the intensity of light emerging from the third polarizer, Is, to the intensity of light incident on the first polarizer, lo? 9,2 ф12 P23
