Question

The velocity of photon is proportional to (where v is frequency)

• A. $\frac{v^2}{2}$
• B. $\frac{1}{\sqrt{v}}$
• C. $\sqrt{V}$
• D. $v$

Answer 1

The correct option is D $v$

Velocity of photon is given by, $c=v\lambda$

where c = speed of light/photon

$\nu$ = frequency of light/photon

$\lambda$ = wavelength of light/photon

Thus for constant $\lambda$,

Velocity of photon, $c\propto \nu$.
