De Broglie's equation is used to show that photons have both particle and wave nature. photons are quantized packets of energy. the wave nature of photons can be proven as they have a wavelength. the particle nature is given by them having both velocity and mass.
de Broglies equation is;
λ = h / p
where λ - wavelength
h - Planck's constant
p - momentum
substituting the values in the equation
p = h/λ
p = 2.20 x 10⁻²⁷ kgm/s
momentum of photon is 2.20 x 10⁻²⁷ kgm/s
