Document Summary
In fizeau"s experiment the rotating wheel contained 720 notches. The figure above shows a ray of light that originates in an aquarium. It travels through water, is incident on the glass side, and emerges into the air. Note: the figure is not drawn to scale. What entry in the table below gives the correct values for the angles shown in the figure: 0. 55 , 27. 3 , 27. 3 , 33. 0 , 27. 3 . Light of wavelength 475 nm in vacuum enters a plastic as shown above. Measurements of the light in the plastic indicate that its wavelength there is 394 nm. A beaker has a height of 30. 0 cm. The lower half of the beaker if filled with water and the upper half is filled with oil. Take nwater = 1. 33 and noil = 1. 48. A person is sitting in a small boat in the ocean. Assume that the person"s eyes are very near the surface of the water.
