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
How do you measure the wavelength of a wave?
Since there are several kinds of waves, there are several ways to measure their frequency. Electrical waves can be measured with a frequency counter, an analog frequency meter or an oscilloscope. Ocean waves' frequency is measured with a stopwatch, but most people who measure ocean waves want to know how large they are rather than how fast they're coming.
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 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.
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.
What units is wavelength measured in usually?
Answer - meters or derivations of meters e.g micrometers, nanometers etc
When light is measured by the distance from crest to crest what is it?
Wavelength
How is the wave length of a light wave be measured?
The wavelength of a light wave is typically measured using a device called a spectrophotometer or a spectrometer. These devices split the light into various wavelengths and measure them with detectors to determine the exact wavelength of the light wave. Wavelength can also be measured indirectly using the speed of light equation, where wavelength = speed of light / frequency.
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 The wavelength of a transverse wave is often measured from?
Crest to trough
What is the wavelength unit of light?
The wavelength unit of light is typically measured in nanometers (nm) or meters (m).
What is the difference between energy and wavelength?
Wavelength is a measure of the length of a wave. Measured in metres. Frequency is a measure of how often something happens, measured in occurrences per second. Energy is the fundamental constituent of the universe, measured in kgm2s-2 or Newton-metres or Joules
How is a wavelength of a wave measured?
The wavelength of a wave can be measured by finding the distance between two consecutive points that are in phase with each other, such as two peaks or two troughs. This distance is typically measured in meters or other units of length depending on the type of wave.
