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 2is 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.
