The maximum possible frequency for which the wave is reflected back for a given distance of propagation in the ionosphere layer is called as_______ Correct Answer Maximum usable frequency

The maximum possible frequency for which the wave is reflected back for a given distance of propagation in the ionosphere layer is called as maximum usable frequency (MUF). For a specified angle there will be a maximum frequency for which the wave is reflected back. If wave exceeds MUF then it’s not reflected back.

A wave is first reflected by a boundary P and then by a boundary Q without dissipating energy. If the boundary P is rigid and the boundary Q is non-rigid, then find the fraction of the amplitude of the reflected wave by boundary P to the reflected wave by boundary Q.
