Light is incident from medium 1 to medium 2 at Brewster's angle equal to 55.4°, and transmitted angle is 34.6°, the permeability of medium 2 is 3/4. 1- Calculate refractive indices for medium land medium 2. 2- Calculate the reflection coefficient for s-polarized. 3- Reflection coefficient for p- polarized.

Attached is the question and the formula to solve it. I attached the formula directly from the book, the Blackbody radiation Pressure formula that is. Thank you :)

A 2.5 m long vane is rotated slowly in a circle. An optical encoder isattached to the vane at its center. It is necessary to know the tipposition of the vane within +/-1 cm. What should be the resolutionof the optical encoder attached to the shaft that positions the vane?

The speed of sound in air is 340 m/s, and the speed of light is 3.0 X 108 m/s. What frequency oflight has the same wavelength as a 200.0 Hz sound wave?
