JEE MAIN - Physics (2007 - No. 5)
Photon of frequency $$v$$ has a momentum associated with it. If $$c$$ is the velocity of light, the momentum is
$$hv/c$$
$$v/c$$
$$h$$ $$v$$ $$c$$
$$hv/{c^2}$$
Explication
Energy of a photon of frequency $$v$$ is given by $$E = hv.$$
Also, $$E = m{c^2},\,\,m{c^2} = hv$$
$$ \Rightarrow mc = {{hv} \over C} \Rightarrow p = {{hv} \over c}$$
Also, $$E = m{c^2},\,\,m{c^2} = hv$$
$$ \Rightarrow mc = {{hv} \over C} \Rightarrow p = {{hv} \over c}$$
