# Which part of the electromagnetic spectrum has the longest wavelength?

## Which part of the electromagnetic spectrum has the longest wavelength?

Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

Which type of electromagnetic wave has the highest frequency the most energy the smallest size?

Gamma rays
Together, these different types of EM radiation make up the electromagnetic spectrum. Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.

### Which part of the wave has the highest frequency?

Gamma rays have the highest frequency.

What is the correct order of the electromagnetic spectrum from shortest wavelength to longest?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

#### What type of energy has the highest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.

Which is the lowest frequency wave in the electromagnetic spectrum?

Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum. Which wave of the electromagnetic spectrum has the longest wavelength and the lowest frequency?

## Which is the longest wavelength of a radio wave?

In Wikipedia there is a very interesting table showing the bands of electromagnetic waves for radio signals. The electomagnetic waves with longest wavelengths belong to the ELF band with wavelengths from 10,000 to 100,000 km, corresponding to frequencies from 3 to 30 Hz.

How are gamma waves arranged in the electromagnetic spectrum?

They are arranged in order of decreasing wavelength (and increasing frequency): Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths.

### How is the electromagnetic spectrum expressed in terms of energy?

The Electromagnetic Spectrum. The electromagnetic spectrum can be expressed in terms of energy, wavelength or frequency. Each way of thinking about the EM spectrum is related to the others in a precise mathematical way. Scientists represent wavelength and frequency by the Greek letters lambda (λ) and nu (ν).
