Radio Waves, frequency - 3 KHz to 300GHz, Waelength-100km to 1mm
Q. Radio Waves have wavelength ranging from- Published on 07 Mar 16a. 100km to 1000km
b. 1mm to 100km
c. 0.1mm to 1mm
d. 1nm to 1mm
ANSWER: 1mm to 100km
- Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies from 300 GHz to as low as 3 kHz.
- Corresponding wavelengths ranging from 1 millimeter to 100 kilometers.
- Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are made by lightning, or by astronomical objects.
- Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, communications satellites, computer networks and innumerable other applications.
