Energy wavelength formula

    • How do you calculate the energy of a wavelength?

      Multiply the speed of light and the Planck constant, and divide the product by the wavelength to calculate the photon energy. For example, yellow visible light photons have a wavelength of about 580 nm or 5.8E-7 m. Thus, their energy is 299,792,458 m/s x 4.13566733E-15 eV s/5.8E-7 m = 2.14 eV.

    • How to calculate a wavelength with the given energy?

      How do you measure wavelength? Use a photometer to measure the energy of a wave. Convert the energy into joules (J). Divide the energy by Planck's constant, 6.626 x 10 -34, to get the frequency of the wave. Divide the speed of light, ~300,000,000 m/s, by the frequency to get wavelength.

    • How to go from energy to wavelength?

      Energy to Wavelength Example First, determine the speed of light. This will be constant at the value of (299,792,458 m/s) Next, determine the plank constant. This will be constant at (6.6261*10^-34) Next, determine the total energy. Calculate the total energy of the photon. Finally, calculate the wavelength. Convert the energy to wavelength using the equation above.

    • What is the difference between wavelength and energy?

      The difference between a long and short wavelength is the distance between two identical points on successive waves. Wavelength is also characteristic of the energy level of a particular wave, with shorter wavelengths being more energetic than longer ones.
