In the figure, a light wave along ray r, reflects once from a mirror and a light wave along ray r2 reflects twice from that same mirror and once from a tiny mirror at distance L from the bigger mirror. (Neglect the slight tilt of the rays.) The waves have wavelength 660 nm and are initially exactly out of phase. What are the (a) smallest, (b) second smallest, and (c) third smallest values of L that result in the final waves being exactly in phase? (a) Number i Units nm (b) Number i Units nm (c) Number Units nm

The attatched figure shows a Michelson interferometer with a movable mirror M1, a fixed mirror M2, and a beam splitter Ms , which is a half-silvered mirror that transmits one-half the light and reflects one-half the light incident upon it independent of the direction of the light. The source emits monochromatic light of wavelength λ. Assume the beam splitter introduces a phase change of π for light that follows path 1 from the source to the detector relative to light that follows path 2 from the source to the detector. Also assume the mirrors M1 and M2 reflect 100% ofthe light incident upon them and the photodetector PM (a photomultiplier) is 100% efficient as well. Question: Use the principles of quantum mechanics to determine the probability that a photon entering the interferometer is detected by the photodetector. Express your answer in terms of the lengths I1 , I2 and λ. Find an expression for I1 in terms of I2 and λ, such that there is 100% probability that the photon is…
Two antennas located at points A and B are broadcasting radio waves of frequency 104.0 MHz. The signals start in phase with each other. The two antennas are separated by a distance d = 8.7 m. An observer is located at point P on the x axis, a distance x = 110.0 m from antenna A. The points A, P, and B form a right triangle. Now observer P walks along the x axis toward antenna A. What is P's distance from A when they first observe fully constructive interference between the two waves?
