The electric field component of a sinusoidal electromagnetic wave traveling through a plastic cylinder is given by the equation E = (5.35(V/m))cos[(1.39x10^7 (rad/m))x-(3.02x10^15(rad/s))t].
Find the frequency, wavelength, and speed of this wave in the plastic.
What is the index of refraction of the plastic?
Assuming that the amplitude of the electric does not change, write a comparable equation for the electric field if the light is traveling in air instead of plastic.
