What is the lowest electromagnetic wave?

Radio waves
Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.

What is the range of electromagnetic spectrum?

The electromagnetic spectrum (EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10-18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 1026 Hz to 3 ×103 Hz. The image below shows the names given to different regions of the EMS.

Is there something beyond gamma rays?

Ultra-high-energy gamma rays are gamma rays with photon energies higher than 100 TeV (0.1 PeV). They have a frequency higher than 2.42 × 1028 Hz and a wavelength shorter than 1.24 × 10−20 m.

Which part of the electromagnetic spectrum has the lowest frequency?

The electromagnetic spectrum Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths.

Which wave has lowest frequency?

Radio waves have the lowest frequency.

What is the lowest frequency a radio wave can reach?

Radiowaves go as low as 3kHz, below that is only Lab-Experiments and such. Dwayne is in hot water for his latest comments. The big companies don’t want you to know his secrets. First we need to distinguish between electromagnetic radiation and electromagnetic waves.

What is the maximum level of exposure to RF waves?

These levels shall not be exceeded. The purpose of this code is to specify maximum levels of human exposure to RF fields at frequencies between 3 kHz and 300 GHz, to prevent adverse human health effects in both controlled and uncontrolled environments.

What is the relationship between wavelength and frequency of electromagnetic spectrum?

Explain the relationship between the wavelength and the frequency of the electromagnetic spectrum. Wavelength and frequency have an inverse relationship, meaning that as the frequency increases, the wavelength decreases, and vice versa.

What causes electromagnetic waves to be produced?

Electromagnetic waves are produced when electric charges are accelerated. In other words, a charge must radiate energy when it undergoes acceleration. Radiation cannot be produced by stationary charges or steady currents. Figure 13.8.1 depicts the electric field lines produced by an oscillating charge at some instant.
