How to calculate the energy of a photon given wavelength

Asked by admin @ 26/11/2021 in Chemistry viewed by 284 People

A photon has a wavelength of 705nm calculate the energy of the photon in joules

Answered by admin @ 26/11/2021

In calculating the energy with a given wavelength, just use
the Planck’s Equation. First calculate for the frequency using the wave
equation. Just divide the speed of light which is 3x10^8 m/s with the given
wavelength (705x10^-9 m). Then multiply the frequency with the Planck constant
which is 6.63 x10^-34 J. The answer would be 2.82x10^-19 J.
