Detailed Solution
Download Solution PDF- Shortwave radio refers to radio broadcasts on a portion of the radio spectrum in the frequency range of 1700 - 30000 kHz (1.7 to 30 MHz).
- Because smaller wavelengths correspond to higher frequencies, shortwave radio received its name because its wavelengths are shorter than the longer wavelengths used in early radio communications.
- Since the length of the antenna is directly proportional to the wavelength, hence short wavelength means the length of the antenna is also short.
- For the short wavelength, high range of frequency is required generally in the range of MHz.
