By an equation. E=MC^2, or energy of a particle equals its mass times the speed of light squared. V=C/(lambda), or frequency equals the speed of light divided by wavelength.
The easiest way is using Planck's constant, which allows you to find frequency and then, by the equations above, wavelength, based on energy calculated by any means.

∙ 12y agoWavelength is simply the length of an individual wave.
So waves are measured in metres.
Light waves in the visible spectrum are very short, wavelengths from 400nm, for violet, to 700nm for red, a nm, nanometre, is one billionth of a metre 0.000 000 001.
Waves in a microwave oven are about 0.12m.
Radio waves cover a wide range;
Longwave radio has waves between 1 and 2 kilometres (1 000 to 2 000metres).
Medium wave, used for AM stations, is around 100 metres.
VHF, very high frequency, used for FM stations around 2 metres.

∙ 14y agoGrammatically, The Question should probably be, " How is wavelength measured?". The answer depends on the particular waves being considered. Wavelength for any repeating wave is the distance between the wave where it starts to repeat. Typically wavelength is measured at the so called "Zero crossings" for electromagnetic (and many other types of) waves.
The techniques used to measure wavelength include radio detectors and counters, zero crossing detectors and radio receivers. If you can convert the wave to an electrical signal, you could also use an oscilloscope. A microphone connected to an oscilloscope for example can let you visually see, and therefore measure the wavelength of sound.
Wavelength proportional to the reciprocal of frequency, the so if you know the frequency (f) then the wavelength is c/f (c is the speed of light). You have to be careful with the units. For example a 600 Khz radio wave has a wavelength of approximately 500 meters (499.65). You have to use the speed of light to get the units right.

Is wavelength measured in hertz or meters?
Usually, no. The wavelength of visible light is usually measured in nanometers. Only larger forms of electromagnetic radiation, like radio waves, are measured in meters.
What units is wavelength measured in usually?
Answer - meters or derivations of meters e.g micrometers, nanometers etc
What is The wavelength of a transverse wave is often measured from?
Crest to trough
What is the unit used to measure radiant energy?
Radiant energy does not exist in quantum units because radiant energy has no wavelength
What is the wavelength of middle C on a piano?
wavelength = velocity/ frequency wavelength = 330/256 wavelength = 1.29 (to 3 sig fig) 1.30
Is wavelength measured in hertz or meters?
Usually, no. The wavelength of visible light is usually measured in nanometers. Only larger forms of electromagnetic radiation, like radio waves, are measured in meters.
Wave lenght is measured from the crest to the trough?
No. The wavelength is measured from crest to crest.
What is music measured by?
Wavelength, amplitude and harmonics
What is meant by vacuum wavelength?
Vacuum wavelength is the wavelength that is measured if the wave is passing through a vacuum. To get the wavelength in a medium you need to know the refractive index.
In what field is De Broglie wavelength being measured?
The De Broglie Wavelength is being measured in the electromagnetic fields. The De Broglie Wavelength theory is related to Bohr's Quantum Theory and is about the energy of atom particles.
How many crests are there in one wavelength?
usually 1 - a crest is the highest tip of a wavelength. But if the wavelength is measured from the highest point them in 1 wavelength there will be 2 crests
How many meters in a wavelength?
The wavelength of a wave is the distance from the crest to the next crest of a wave, usually measured in metres. A wavelength is not a unit.
How is the path length of an infrared cell measured?
in wavelength
When light is measured by the distance from crest to crest what is it?
Wavelength
What units is wavelength measured in usually?
Answer - meters or derivations of meters e.g micrometers, nanometers etc
What do you mean by using the word wavelength?
The word "wavelength" refers to the frequency of a wave. Wavelength is measured in hertz; the number of vibrations per second.
What is measured from crest to crest of a transverse wave?
That would be the wavelength, it can also be measured from trough to trough.
