  • How do you calculate the wavelength of light?

  • Calculating wavelength is dependent upon the information you are given. If you know the speed and frequency of the wave, you can use the basic formula for wavelength. If you want to determine the wavelength of light given the specific energy of a photon, you would use the energy equation.

  • How is the energy of a particle related to wavelength?

  • The energy of any body is related to its wavelength by the equation The energy is inversely proportional to the wavelength of the light. The lessened the wavelength, the more is the energy of the particle in a wave. Problem 1: Calculate the energy of the photons emitting red light. Consider the wavelength of the beam of red light to be 698 nm.

  • How do you find the energy of a photon from its wavelength?

  • This example problem demonstrates how to find the energy of a photon from its wavelength.To do this, you need to use the wave equation to relate wavelength to frequency and Planck’s equation to find the energy. This type of problem is good practice at rearranging equations, using correct units, and tracking significant figures.

  • What is the wavelength of beam of light?

  • The beam of light is of wavelength 422.2 nm. The energy possessed by a photon is termed as photon energy, and is inversely proportional to the electromagnetic wave of the photon, by the relation Hence, the photon with a large wavelength possesses a small unit of energy whereas the photon with a smaller wavelength gives a large amount of energy.
