Q. The linear momentum of photon is p. The wavelength of photon is $\lambda\ ,$ then (h is Planck constant)
A) $\lambda = hp$
B) $\lambda = \frac{h}{p}$
C) $\lambda = \frac{p}{h}$
D) $\lambda = \frac{p^{2}}{h}$
Explanation
(b) Momentum of photon, $p = \frac{h}{\lambda}$
Therefore, wavelength of photon, $\lambda = \frac{h}{p}$
