EE 164 Problem Set 1 Spring 2004 Problem 1An optical ray with 0λof 640nm traveling through another medium measures a wavelength of 427nm. a) Find Index of refraction of the other medium ()2nb) Find the Velocity of the ray in the other medium ()2vc) Find the angle of incident 1θif the angle of refraction 2θis equal to 33°Problem 2An optical beam travels through a glass tube filled with Helium gas. If the combined attenuation due to absorption and scattering ()abaa+is equal to 7.2 and the ratio of the output/input ()/oinIIintensities is 0.354, compute the length ()dof the tube.
