b. The light emitted by the Sun is mostly yellow so that its wavelength is about 550 nm. What is its frequency?
c. The distance between the Earth and the Sun is about 149 million kilometers. How long does it take for the light to travel this distance?
d. A polarizer is placed in the xy-plane. Its polarization axis coincides with the x-axis. The z-axis is taken as the line of sight when looking at the Sun. What is the direction of the transmitted light electric field? What is the direction of the transmitted magnetic field? Sketch the direction of light propagation, the direction of the electric field, and the direction of the magnetic field of the transmitted light.
e. The intensity per unit we receive from the sun is about1413W/m^2. What is the intensity of the transmitted light after the polarizer?
f. If you could look only at the light after it had been reflected, say, by the sea (and NOT AT ALL at the direct radiation), what would you see?
