Question

Which is the incorrect statement of the following? (A) Photon is a particle with zero rest mass (B) Photon is a particle with zero momentum (C) Photons travel with velocity of light in vacuum (D) Photons even feel the pull of gravity

Tardigrade Admin · Accepted Answer

Photon moves with speed of light ie, v = c and rest mass of a particle is m0=m√1-v2/c2 hence m0(photon)=0 ∴ photon has zero rest mass. Momentum of photon = (h/λ)

Q. Which is the incorrect statement of the following?

Photon is a particle with zero rest mass

Photon is a particle with zero momentum

Photons travel with velocity of light in vacuum

Photons even feel the pull of gravity

Photon moves with speed of light ie,
v = c and rest mass of a particle is
$m_{0}$ =m $1 - v^{2} / c^{2}$
hence $m_{0}$ (photon)=0
$∴$ photon has zero rest mass.
Momentum of photon = $\frac{h}{λ}$
