Calculate the mass of a photon with wavelength 3.6 Å.

Text Solution

Verified by Experts

`lamda=3.2`Å=`3.2xx10^(-10)m`
Velocity of photons (v)=velocity of light
`=3xx10^(8)m*s^(-1)`
From de Broglie equation, `lamda=(h)/(mv)`
or, `m=(h)/(lamdav)=(6.626xx10^(-34))/((3.2xx10^(-10))xx(3xx10^(8)))=6.9xx10^(-33)kg`
