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.
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.
Answer - meters or derivations of meters e.g micrometers, nanometers etc
Crest to trough
Radiant energy does not exist in quantum units because radiant energy has no wavelength
wavelength = velocity/ frequency wavelength = 330/256 wavelength = 1.29 (to 3 sig fig) 1.30
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.
Wavelength, amplitude and harmonics
The samples will be measured at a specific wavelength using the spectrophotometer.
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.
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.
Wavelength

The word "wavelength" refers to the frequency of a wave. Wavelength is measured in hertz; the number of vibrations per second.
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.
Crest to trough
For visible light, the wavelength will usually be specified in nm (nanometers).
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
