If h is Plank's constant. Find the momentum of a photon of wavelength 0.01Å.

A

`10^(-2) h`

B

h

C

`10^2 h`

D

`10^(12)h`

Text Solution

Verified by Experts

The correct Answer is:
D
Momentum of photon , `p = E/c = (hupsilon)/c`
where E is the energy of a photon and c is the velocity of light .
`:. P = (hc)/(clamda) " "[ :. upsilon =c/lamda]`
`=h/lamda =(h)/(0.01 xx 10^(-10) ) = 10^(12)h`
