Energy from the Sun arrives at the top of the Earth's atmosphere with an intensity of 1.30 kW/m2. How long does it take for 2.39 109 J of energy to arrive on an area of 1.00 m2? This is the average monthly electrical energy consumption of a family of four in the United States.
Two wires, each of length 1.7 m, are stretched between two fixed supports. On wire A there is a second-harmonic standing wave whose frequency is 618 Hz. However, the same frequency of 618 Hz is the third harmonic on wire B. Find the speed at which the individual waves travel on each wire.
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.…
