Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhich radio is commonly used for high frequency communications?
VHF – Very High Frequency Very high frequency is commonly used for FM radio broadcast, two-way land mobile radio systems, long-range data communication, and marine communications, just to name a few. VHF includes radio waves from 30 MHz to 300 MHz.

High frequency light has short wavelengths and high energy. X-rays or gamma-rays are examples of this.
Read moreWhat is frequency in very short answer?
Frequency describes the number of waves that pass a fixed place in a given amount of time . So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.
Read moreWhat is a frequency in basic science?
In the most general sense, frequency is defined as the number of times an event occurs per unit of time . In physics and chemistry, the term frequency is most often applied to waves, including light, sound, and radio. Frequency is the number of times a point on a wave passes a fixed reference point in one second.3 May 2019
