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?
Astronomers observe the chromosphere of the Sun with a filter that passes the red hydrogen spectral line of wavelength 656.3 nm, called the H, line.
