Title: Re: A line in the spectrum of atomic mercury has a wavelength of 258 nm. When mercury emits a photon ... Post by: kdot14 on Feb 1, 2023 The wavelength and frequency of all types of waves (not just electromagnetic waves) are related according to the equation:
wavespeed = wavelength * frequency For a photon, the wave speed is the speed of light = 2.998*10^8 m/s, so wavelength = (2.998*10^8 m/s)/(254*10^-9 m) wavelength = 1.18*10^15 Hz |
