Quiz 1 (Total: 5 points + 1 points bonus) March 7, 2008 1. (1.5 pts.) What is wave-particle duality of light? Describe two experiments to show that light has wave-particle duality. 2. (1 pts.) A Ray of yellow light from sodium discharge lam falls on the surface of a diamond in air at 45 ° . If at that frequency n diamond =2.42, compute the angular deviation suffered upon transmission. 3. (1.5 pts.) (a) Under paraxial ray approximation, show that the Gaussian imaging formula for a spherical interface between a medium of refractive index n and one of refractive index n’ is R n n s n s n i o = + ' ' . (Here s o , s i and R are objective distance, image distance and radius of spherical interface, respectively)
