Light, being a vibrating electro-magnetic wave, has a frequency of vibration.
Light, being a vibrating electro-magnetic wave, has a frequency of vibration.
Tachyons are theorised to be the fastest particle in the universe their slowest speed being the speed of light. But until they are proven to exist, light is the fastest thing in the universe.
The most important piece of evidence that shows that the universe is in motion is the Doppler Effect, also termed the red shift. This basically means that objects headed away the observer will have their light bent toward the "red" (lower frequency) side of the light spectrum while objects headed toward the observer will have their light bent toward the "blue" (higher frequency) end of the spectrum. By using the Doppler Effect we are able to that the majority of the universe is in motion, expanding outward.
Frequency can be found in sound, light, and line current. An example of frequency is, the frequency wave of light will determine what color the light is.
Frequency controls the color of the light.

Yellow light has the lower frequency.
Light is absorbed by the molecule.
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.
Its wavelength (or frequency).
When the big bang theory started the universe, light was created.
