You need to know speed and frequency. The speed of all photons is the speed of light, 3.0 x 108m/s. The equation for finding wavelength when frequency and speed are known is λ = ƒ/c , where c is the speed of light, f is the frequency in Hz, and λ (Greek letter lambda) is the wavelength in meters.
The energy of a photon is directly proportional to the frequency. Since the frequency is inversely proportional to the wavelength, the energy, too, is inversely proportional to the wavelength.
UV has a wavelenght of 400nm and less you can calculate the frequency with this formula V (frequency) = c (speed of light) / λ (wavelenght)
The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
The energy of the photon is 3,1631.e-19 joule.
Multiply (Planck's constant) times (the speed of light), and divide the result by the photon's wavelength.Be careful to keep the units consistent.

You need to know it speed, wavelenght and its frequency.
The energy of this photon is 3,7351.10e-19 joules.

Photon Energy E=hf = hc/w thus wavelength w= hc/E or the wavelength is hc divided by the energy of the photon or w= .2 e-24 Joule meter/Photon Energy.
Multiply (Planck's constant) times (the speed of light), and divide the result by the photon's wavelength.Be careful to keep the units consistent.
light consist of many wavelenght and different wavelenght will be absorb by different object leaving certain wavelenght to escape and thus the colour of the object is shown
