Photon Momentum
Easyphysics
Photon momentum p (wavelength λ) is:
Select the correct option:
Solution
Incorrect! Answer:
h/λ
Photons have zero rest mass, but they possess momentum and energy.
- E=hf
- E=pc Equating the two: pc=hf⟹p=chf=λh. This confirms that radiation carries momentum and can exert pressure (Radiation Pressure) when it hits a surface.
