Question

1. Cirele the correct answer a. (5 pts) Which of the following CAN be explained by wave optics but NOT by ray optics? A. Young's double-slit experiment C. Newton's rings (a type of interference patterns): D. Huygens' principle. Ib. (5 pts) The antireflection coating is based on A. Total internal reflection B. Incidence at the Brewster angle; C. Wavefront-splitting interference; D. Amplitude-splitting interference. 2. Answer the following questions 2a. (10 pts) The profile (-0 s) of a wave is given by (x)-2 To. The wave is propagating towards the x direction at a speed of 3 m/s. Write down the wave function. 2b. (10 pts) Consider a medium with ? 45, ?-74, where co,? are the vacuum permittivity and permeability, respectively. What is () the refractive index of the medium, (ii) the speed of light in the medium, and (ii) the impedance of the medium? 2c (10 pts) Describe clearly a method to rotate the horizontal electrical field of a laser beam to the vertical direction?

Explanation / Answer

1C). Newton's ring can be explained by wave optics but not by ray optics...

2A). The antireflection coating is based on Total internal reflection..

Because it will effect the total internal reflection.
