Optical isolator. consider a system consisting of a perfect horizontal transmission polarizer, followed by a quarter wave plate with its fast axis oriented at +45 degrees, followed by a retroreflecting mirror. 4. a. assuming that the waveplate is exactly quarter wave at the operating wavelength, what is the reflection backwards through the polarizer? why?

Apossible explanation for a set of facts that can be tested by further investigation is called

Gunpowder residue is most likely to show up where on a shooters hands

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
