If h is Planck’s constant, the momentum of a photon of wavelength 0.01 Å is: |
$10^{-2}h$ h $10^{2}h$ $10^{12}h$ |
$10^{12}h$ |
Momentum of photo, $p=\frac{E}{c}=\frac{hv}{c}$ Where E is the energy of a photon and c is the velocity of light. $∴p=\frac{hc}{cλ}$ $[∵v=\frac{c}{λ}]$ $=\frac{h}{λ}=\frac{h}{0.01×10^{-10}}=10^{12}h$ |
