When a wave is reflected in the same medium (like water of the same depth), what can be said about the (a) velocity of the wave; (b) frequency of the wave; (c) wavelength? Why?
The ionosphere is the ionized part of the upper layer of the earth's atmosphere. The air molecules there are ionized by solar radiation.
This layer of the atmosphere is a fairly good conductor, and radio waves are often "bounced" off the bottom of the ionosphere back
toward the earth, in a process called skip or skywave propagation. Due to these properties, the space between the surface of the earth
and the bottom of the ionosphere acts like a closed wave guide that will exhibit resonance for very low frequencies. Resonance
excitations in the cavity are caused by lightning strikes, which hit the earth about 50 to 100 times a second. These low atmospheric
resonance frequencies are known as Schumann resonances, named after the physicist Winfried Otto Schumann, who first calculated
them in 1952. There are several Schumann frequencies that occur in the low frequency background, which ranges from 3 to 60 Hz. The
highest intensity resonance mode (called the fundamental) occurs at 7.83 Hz.…
