Wave OpticsWave Superposition/Interference: Use the principle of wave superposition to explain how a propagated wave with a fixed amplitude may increase in amplitude AND decrease in amplitude. Relate this principle to explain how Thomas Young's double-slit experiment proved the wave nature of light.

Physics
Wave OpticsA film of soapy water (n = 1.33) on top of a sheet of crown glass (n = 1.52) has a thickness of 196 nm. What wavelength is most strongly reflected if it is illuminated perpendicular to its surface? (This is the apparent color of the soapy film.) nm

Physics
Wave OpticsYoung's double slit experiment is one of the quintessential experiments in physics. The availability of low cost lasers in recent years allows us to perform the double slit experiment rather easily in class. Your professor shines a green laser (560 nm) on a double slit with a separation of 0.111 mm. The diffraction pattern shines on the classroom wall 3.5 m away. Calculate the fringe separation between the second order and central fringe.

Physics
Wave OpticsWorking in lab class you shine a green laser (5.40 x 10² nm) onto a double slit with a separation of 0.320 mm. What is the distance between the first and second dark fringe that shines on the wall 1.80 m away?

Physics
Wave OpticsWhile direct sunlight is unpolarized, light coming from a clear blue sky is linearly polarized to some extent. Assume all the light from the blue sky is linearly polarized in the same direction. Suppose a school library has installed skylight windows in the ceiling of the atrium to allow for natural lighting. The windows are polarized so that the intensity of the light, after passing through the windows, is 62% of the original intensity of the light from the blue sky. What is the angle between the polarization direction of the light and the polarization axis of the windows?

Physics
Wave OpticsYou've entered the Great Space Race. Your engines are hearty enough to keep you in second place. While racing, the person in front of you begins to have engine troubles and turns on his emergency lights that emit at a frequency of 5.570 × 10^14 Hz. If the person in front of you is traveling 2612 km/s faster than you when he turns on his lights, what is the frequency of the emergency lights that you observe when it reaches you in your spaceship? (Enter your answer to four significant figures.)

Physics
Wave OpticsIn a Newton's Ring experiment, the diameter of the 20th dark ring was found to be 5.82 mm and that the 10th ring 3.36 mm . If the radius of the planoconvex lens is 1 m, calculate the wavelength of light used

Physics
Wave OpticsFind a lighted bare light bulb (in your room or a streetlight, etc). Move around and notice that you can see the lighted bulb from many directions. 1) Now cut a narrow slit along the dashed line below. Hold the paper at arm's length between your eye and the bulb, i.e., you should not look from the edges of the paper. Can you still see the bulb from many directions? Where must you place your eye so you can see the bulb?
