Which electromagnetic wave can travel the lowest frequency?

Which electromagnetic wave can travel the lowest frequency?

Radio waves
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 is the wavelength of an electromagnetic wave that has frequency of 1 Hz?

3*10^8m
Answer and Explanation: The wavelength of an electromagnetic wave that has a frequency of 1Hz is 3*10^8m.

Is there a limit to the frequency of electromagnetic waves?

The electromagnetic spectrum has no theoretical limit at either end. At the other end of the spectrum, it takes higher energies to create higher frequencies (shorter wavelengths). That means you are limited only by the energy available.

Does velocity depend on frequency?

The small variations in the values for the speed were the result of experimental error, rather than a demonstration of some physical law. The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant.

How do you describe an electromagnetic wave with 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. In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz.

Which of these electromagnetic waves has the shortest wavelength?

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.

What is the maximum possible frequency?

The most energetic gamma ray ever “measured” is 320 EeV, which comes out to 7.74 x 10^34 Hz. In this case it was a 1.4 sigma or about 60\% chance that it was a really a cosmic ray. The absolute upper limit for a photon is 6.04 x 10^102 Hz. This limit is a fundamental law of the universe established by Isaac Asimov.

Is there a limit to frequency?

No, there isn’t. The frequency of a light wave is a frame-dependent quantity, and you can change the frame of reference to make the frequency arbitrarily low/high. Since all frames of reference are equally valid, there can be no lower or upper limit in frequency.

What is the relationship between frequency wavelength and velocity?

When the wavelength of the wave increases and the frequency is constant, the velocity of the wave also increases because the wavelength is directly proportional to velocity. When the frequency of a wave increases and the wavelength is constant, the velocity of the wave increases.

How will you relate the frequency and the velocity of a wave?

The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The frequency is the same as that of the source and is the number of waves that pass a point per unit time.

What is the relationship between frequency and wavelength in electromagnetic waves?

A David mentioned, EM can be a frequency less than 1Hz. There is a relationship between the wavelength and frequency. So when wavelength decreases then frequency increases. And vice versa. When wavelength increases then frequency decreases. The propagation speed in a vacuum is equal for all EM waves.

What are the different types of electromagnetic waves?

Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014Hz.

What is the speed of electromagnetic waves in free space?

The speed of any electromagnetic waves in free spaceis the speed of lightc = 3*108 m/s. long as λf = c. When electromagnetic waves travel through a medium, the speed of the waves in the medium is v = c/n(λfree), where n(λfree) is the index

What is the wave number and frequency of a periodic wave?

The wave number is k = 2π/λ, where λ is the wavelength of the wave. The frequency f of the wave is f = ω/2π, ω is the angular frequency. The speed of any periodic wave is the product of its wavelength and frequency.
