As we discussed in concept

Kinetic mass of photon -

m=\frac{E}{c^{2}}= \frac{h}{c\lambda }

- wherein

m\rightarrow mass \: of\: photon

c\rightarrow speed \: of\: light

h\rightarrow plank's \: constant

\fn_jvn \lambda -wave\: length

 

 

 

 For photon E = pc.

=> p=\frac{E}{c}=\frac{h \nu}{c}

 


Option 1)

\frac{hv}{c}

This option is  correct.

Option 2)

\frac{c}{hv}

This option is incorrect.

Option 3)

hv

This option is incorrect.

Option 4)

\frac{hv}{c^{2}}

This option is incorrect.
