282. assignment (electromagnetic wave)

A polarized plane wave is described by the following equations:

E=E0sin[(10^14 s^-1)t-kz]x’

B=(10^-6T)sin[(10^14s^-1)t-kz]y’

where x’ and y’ are unit vectors. Notice that I have not specified a numeric value for E0 and k.

A. In which direction do these electromagnetic fields propogate?

B. What is the numerical value of E0? Be sure to include units.

C. What is the wavelength of this radiation, in meters? Could you see this with your eyes? If not, what sort of radiation is it?

D. What is the intensity of this radiation?

E. What would the intensity of light be after passing through three polarizing filters rotated at 10°, 20°, and 30° from the positive x-axis?
