Which of the following electromagnetic waves has the lowest 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.

What color wave has the lowest frequency?

red

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 waves have a low frequency?

Extremely low frequency (ELF) is the ITU designation for electromagnetic radiation (radio waves) with frequencies from 3 to 30 Hz, and corresponding wavelengths of 100,000 to 10,000 kilometers, respectively.

What are the 7 types of waves?

What type of electromagnetic waves is used in radar?

18.1 Radar Frequency Bands. Radar systems transmit electromagnetic or radio waves. Most objects reflect radio waves, which can be detected by the radar system.

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.

What is very low frequency used for?

Very Low Frequency (VLF) communications transmitters use digital signals to communicate with submerged submarines on at frequencies of 3-30 kHz. The eighteen Trident submarines constitute about half the US strategic nuclear capability.

Does low frequency have high energy?

A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.

What is considered a low frequency?

Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz. Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications.

What are the 2 types of waves?

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

What are the classification of waves?

There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.

What type of waves are light waves?

Light waves move as transverse waves (see diagram of a transverse wave) and can move through a vacuum (empty space) at a speed of approximately 186,000 miles per second. Light has both magnetic and electric fields. Scientists call this electromagnetic radiation (light).
