What are the shortest waves in the electromagnetic spectrum?

Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

What are the shortest waves and an example on the electromagnetic spectrum?

This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave. The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

What type of electromagnetic waves are the shortest?

Gamma rays have the shortest wavelengths of the electromagnetic spectrum, and the highest energies. Gamma rays have such short wavelengths, that astronomers usually discuss them in terms of energy. Gamma rays have energies greater than about 100 keV (keV stands for kilo-electron volt.

What are the 7 electromagnetic waves in order?

This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

What types of EM energy have short wavelengths?

Electromagnetic energy travels as waves that vary in wavelength. Radio waves and microwaves lie at the longer end of the spectrum of electromagnetic energy (kilometers and meters to centimeters and milimeters), while x rays and gamma rays have very short wavelengths (billionths or trillionths of a meter).

What color has the highest energy?


What are the 7 types of waves?

Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.

  • Radio Waves: Instant Communication. …
  • Microwaves: Data and Heat. …
  • Infrared Waves: Invisible Heat. …
  • Visible Light Rays. …
  • Ultraviolet Waves: Energetic Light. …
  • X-rays: Penetrating Radiation. …
  • Gamma Rays: Nuclear Energy.

What color has the least energy?


What is the highest frequency?

Audio frequencies are expressed in hertz (Hz); although experts don’t always agree on specific values, the overall consensus is that high-frequency sounds start at 2,048 Hz. Moving backward, the range between the lowest treble and 256 Hz is known as midrange audio.

Which electromagnetic wave has the highest energy?

Gamma rays

What part of the visible spectrum has the highest energy?

Violet waves

Where do radio waves fall on the electromagnetic spectrum?

Most of the radio part of the EM spectrum falls in the range from about 1 cm to 1 km, which is 30 gigahertz (GHz) to 300 kilohertz (kHz) in frequencies. The radio is a very broad part of the EM spectrum. Infrared and optical astronomers generally use wavelength.

Which type of waves has 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.

Is the electromagnetic spectrum infinite?

In general the frequency spectrum for Electromagnetic (e.g light, radio, etc) is continuous and thus between any two frequencies there are an uncountable infinity of possible frequencies (just as there are an uncountable number of numbers between 1 and 2).

What is the fastest electromagnetic wave?

Radio Waves

Does higher frequency mean higher energy?

Frequency –> Energy

The higher the frequency of light, the higher its energy. We know from the problems above that higher frequencies mean shorter wavelengths. … High frequency light has short wavelengths and high energy. X-rays or gamma-rays are examples of this.
