AM stands for amplitude modulation (the kind used in the am broadcast band and also on the shortwave bands).The shortwave bands begin just a little higher than the top of the am broadcast band and go up to 30000 KHz. The am broadcast band is from 530 to 1700 KHz and shortwave broadcast bands begin about 2000 KHz. The programming on shortwave stations is many types such as cultural,news,science,and just about anything about the country which the station is broadcasting from.Between the shortwave broadcast bands you can also hear amateur radio operators,military,utility stations,radio beacons,pirate broadcasters,radio telephone,aircraft, radio teletype,and lots more.The higher bands (above about 9000KHz) are daytime bands because the signals there propagate around the world in the daytime and the lower bands below about 9000 KHz are nighttime bands and you listen there from about sunset to sunrise.I could go on forever but that is probably about as you want to know about it unless you have ever listened, once you have experienced shortwave listening when conditions are right, you will be hooked on a great hobby.

DevinAM (amplitude modulation) and shortwave are both radio frequency bands used for broadcasting. AM is typically used for local and regional radio broadcasting, while shortwave is used for long-distance communication and international broadcasting. Shortwave signals can travel much farther distances due to their ability to bounce off the Earth's ionosphere.

What is difference between shortwave and microwave?
Shortwave refers to radio frequencies ranging from 1.6 MHz to 30 MHz, used for long-distance communication. Microwaves have higher frequencies (1 GHz to 300 GHz) and are used for various applications such as telecommunications, cooking, and radar systems. Both shortwave and microwaves are forms of electromagnetic radiation, but they differ in frequency range and applications.
What is the wavelength of shortwave radiation?
Shortwave radiation typically refers to solar radiation, which has a wavelength range between 0.1 to 4 micrometers. This includes ultraviolet (UV), visible, and near-infrared light. Each type of radiation within this spectrum has a specific range of wavelengths.
What happens to the shortwave radiation that reaches Earth's surface and is not reflected?
The shortwave radiation that reaches Earth's surface and is not reflected is absorbed by the surface, warming it up.
What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the equation for calculating the phase difference between two waves?
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
