FAQ

Those who are looking for an answer to the question «What is the frequency of an electromagnetic wave if it has a wavelength of 1 km?» often ask the following questions:

👋 How are frequency and wavelength of an electromagnetic wave related?

The higher the frequency, the shorter the wavelength. In all electromagnetic waves, frequency(in hertz) times wavelength (in meters) equals to 300 000 000 meters per second (wave speed).

👋 How are wavelength and frequency of an electromagnetic wave related?

  • When the frequency is multiplied by the wavelength, it yields the speed of the wave. Electromagnetic waves always move at the same speed in a vacuum, known as the speed of light. It equals 299,792,458 meters per second. Light is an electromagnetic wave, and as such has frequency and wavelength.

👋 Which electromagnetic wave has the longest wavelength and lowest frequency?

Radio Waves -- The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves.

How do you find the frequency and wavelength of an electromagnetic wave?

So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light. FYI, λ is the Greek letter lambda , and ν is the Greek letter nu (it is not the same as a v). To find wavelength ( λ ), the equation is manipulated so that λ=cν .

Which type of electromagnetic wave has the longest wavelength and lowest frequency?

Radio waves have the lowest frequency and longest wavelength there arent any sub-catagories it just goes (lowest to highest in frequency) Radio wave, microwave, infrared, Visible light, ultra violet light, x-ray, then gamma ray with the shortest wavelength and highest frequecy

What happens to the frequency when the wavelength of an electromagnetic wave goes up?

As wavelength goes up, the frequency comes down.

What is frequency of an electromagnetic wave if it has a wavelength of 1.0km?

You need to the speed of the wave (the speed of light) by the wavelength. Be sure to convert everything to compatible units first; for example, you may need to convert the km to meters.

What is the relationship between the frequency and the wavelength of each electromagnetic wave?

frequency x wavelength = speed of the wave. This applies to all waves, not just to electromagnetic waves.

What is the wavelength of an electromagnetic wave that has a 1 hz frequency?

Wavelength = speed/frequency = 300 million meters

What is the wavelength of an electromagnetic wave that has a frequency of 1hz?

Wavelength = speed/frequency = 300 million meters per second/1 per second = 300 million meters.

Which electromagnetic wave has the longest wavelength shortest wavelength?

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

What electromagnetic wave has the highest frequency?

Gamma-rays

What electromagnetic wave have the lowest frequency?

radio waves

As the wavelength of an electromagnetic wave decreases how does its frequency vary?

As the wavelength of an electromagnetic wave decreases, its frequence increases. This is true not only for electromagnetic waves, but for mechanical wave and matter wave as well.

What's the wavelength of an electromagnetic wave has a frequency of 425000 hz?

425,000 Hz: λ = about 0.438 miles.

How are frequency and wavelength of electromagnetic waves related?
  • All electromagnetic waves are just light photons, so they travel at the speed of light c, and so we get, Since the speed of light in an empty space, a vacuum, is constant, we can define the equation as, where k is a constant. So, the frequency is inversely proportional to the wavelength. Increasing wavelength decreases frequency, and vice-versa.
What is the wavelength of an electromagnetic wave?

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.

Which electromagnetic wave has highest frequency?

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

What is the frequency of an electromagnetic wave that has a wavelength of 300000 kilometers?

Frequency = (speed) / (wavelength) = (3 x 108) / (3 x 108) = 1 Hz

What is the wavelength of an electromagnetic wave that has a frequency of 1 hz?

The distance light takes to travel in a second (just less than 30000000metres).

What is the wavelength of an electromagnetic wave that has a frequency of 3 khz?

The wavelength is w=c/f = 3E9/3E3 m = 1E6 meters.

What is the wavelength of an electromagnetic wave that has a frequency of 3 kilohertz?

Wavelength = (speed)/(frequency) = 300,000,000m/s/3,000(1/s) = 100,000 meters or 100 km

What is the wavelength of an electromagnetic wave that has a frequency of 3 mhz?

An electromagnetic wave has a velocity "c", the universal wave equation velocity = wavelength * frequencythe wavelength then equal c / frequencythen the wavelength of that wave is : Lambda= c / Nu= 299792458 / 3*1000000 = 99.930819333333333333333333333333 meters ~ 100 meters(Lambda is the wavelength, Nu is the frequency).====================================To summarize:Wavelength = (speed) / (frequency) = (3 x 108) / (3 x 106) = 102 = 100 meters, in vacuum

What is the relationship between wavelength and frequency of electromagnetic waves?
  • B) The wavelength is inversely proportional to the speed of the wave. C) The wavelength is the same for all types of electromagnetic waves. D) The wavelength is directly proportional to the frequency of the wave. E) The wavelength is inversely proportional to the frequency of the wave. 9.
