Originally Answered: Why do we use high frequency waves as carrier waves? HF (2 – 30 MHz) is used for long distance communications because the atmosphere acts to bend these rays and bounce them back towards earth, so that they can travel all over the world, using very modest power to do so .
Read moreWhich frequency is best for communication?
Digital communication systems such as Bluetooth and some of the 802.11 protocols operate in the low-gigahertz range, more specifically, at frequencies near 2.4 GHz . These are generally short-range systems, but they offer reliable communication and the high carrier frequency enables high data rates.
Read moreWhat is S band and L band in radar?
L band radars operate on a wavelength of 15-30 cm and a frequency of 1-2 GHz. L band radars are mostly used for clear air turbulence studies. S band radars operate on a wavelength of 8-15 cm and a frequency of 2-4 GHz. Because of the wavelength and frequency, S band radars are not easily attenuated.
Read moreWhy are gamma rays highest frequency?
Gamma rays are radiation from nuclear decay, when a nucleus changes from an excited energy state to a lower energy state. Gamma rays are typically waves of frequencies greater than 1019 Hz. They have high energies (greater than 10 4 eV per photon) and extremely short wavelengths (less than 10 −14 m) .

Read moreAre gamma rays the highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies . Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Read moreHow do you find the frequency of gamma rays?
(A) The frequency of gamma rays is given as: f1=6.90×1021 Hz f 1 = 6.90 × 10 21 H z . The speed of all electromagnetic waves is: {eq}c = 3 \times…
