Question A3
Light is incident from air onto a flat surface of glass of refractive index ng = 1.55.
At normal incidence (0, = 0), calculate the fraction of the incident power reflected from the glass.
Also, calculate the Brewster angle at which the reflectance for the TM polarisation is zero.

A uniform plane wave is generated from a ham radio antenna on earth. The take off angle is 60 degrees (the angle ffrom ground going up is 60 deg). Using simple trigonometry the angle if incidence with the ionosphere would be 30 degrees. Assume the F layer of the ionosphere is 300 km above the earth. The wave frequency from the transmitter is 21 MHz. WIll this wave refract off the ionosphere and end up somewhere on earth? If yes, what is the distance it travels?
