Vedclass · Answer

(C) The momentum $p$ of a photon is given by the formula $p = \frac{h}{\lambda}$.Since the speed of light $c = 
u \lambda$,we have $\lambda = \frac{c}{
u}$.Substituting this into the momentum formula,we get $p = \frac{h
u}{c}$.Given values are frequency $
u = 10^9 \ Hz$,Planck's constant $h = 6.6 	imes 10^{-34} \ J \cdot s$,and speed of light $c = 3 	imes 10^8 \ m/s$.$p = \frac{(6.6 	imes 10^{-34} \ J \cdot s) 	imes (10^9 \ Hz)}{3 	imes 10^8 \ m/s}$.$p = \frac{6.6}{3} 	imes 10^{-34 + 9 - 8} \ kg \ m/s$.$p = 2.2 	imes 10^{-33} \ kg \ m/s$.

What is the momentum of a photon with a frequency of $10^9 \ Hz$?

The radiation with frequency $1.0 \times 10^{14} \ Hz$ lies in the infrared region. The energy of one photon of this radiation in joules is:

$A$ photon creates an electron-positron pair with equal kinetic energy. If the kinetic energy of each particle is $0.29 \ MeV$,the energy of the photon must be .......... $MeV$.

The energy $E$ and momentum $p$ of a moving body of mass $m$ are related by a specific equation. Given that $c$ represents the speed of light,identify the correct equation.

An electron and a photon have the same wavelength of $10^{-9} \, m$. If $E$ is the energy of the photon and $p$ is the momentum of the electron,then the magnitude of $E / p$ (in $SI$ unit) is
