A monochromatic light source with a power output of 56.0 W radiates light of wavelength 630 nm uniformly in all directions.

Unpolarized light with intensity 350 W/m² passes first through a polarizing filter with its axis vertical, then through a second polarizing filter. It emerges from the second filter with intensity 131 W/m². What is the angle from vertical of the axis of the second polarizing filter?

The GPS (Global Positioning System) satellites are approximately 5.18 m across and transmit two low-power signals, one of which is at 1575.42 MHz (in the UHF band). In a series of laboratory tests on the satellite, you put two 1575.42 MHz UHF transmitters at opposite ends of the satellite. These broadcast in phase uniformly in all directions. You measure the intensity at points on a circle that is several hundred meters in radius and centered on the satellite. You measure angles on this circle relative to a point that lies along the centerline of the satellite (that is, the perpendicular bisector of a line which extends from one transmitter to the other). At this point on the circle, the measured intensity is 2.00 W/m². At how many other angles in the range 0° < 0 < 90° is the intensity also 2.00 W/m²? Express your answer as an integer. N = Submit Part B 0 = Submit 2 Find the four smallest (positive) angles in the range 0° < 0 < 90° for which the intensity is 2.00 W/m². Express your…

A microscope contains two polarizers, one below the stage to polarize the light and another polarizer (the analyzer) between the objective lens and the eyepiece. (a) White light with an intensity of 50 W/m2 is passed through the two polarizers in the microscope. If the analyzer is at an angle of 60° to the first polarizer. What is the intensity of light reaching the eyepiece? (b) The microscope is used to inspect a block of Si (n = 3.5) which is coated with a thin layer (t = 200 nm) of SiO (n = 1.45). What is the longest wavelength of light reflected strongly and thus not transmitted through the sample?
