Explanation
- Energy of photon will be equal to that of the electron = E
- Because the energy in the waveform depends on the frequency or wavelength only.
- We use the formula for De Broglie's wavelength = lambda = h c / E Because: E = Kinetic energy of electron = h vv = frequency of photon /electron waveform v = c / wavelength c = speed of light = 3 ×10^8 m/sh = Planck's constant = 6.626 × 10^-34 J-s.
