If the total energy of radiation of frequency `10^(14)Hz` is `6.63J`, calculate the number of photons in the radiation.
(Planck's constant `=6.63xx10^(-34)J-s`).

Text Solution

Verified by Experts

Given, `E=6.63J,h=6.63xx10^(-34)Js,v=10^(14)Hz`
`:.` No. of photons (n) `=(E)/(hv)`
`n=(6.63)/(6.63xx10^(-34)xx10^(14))`
`n=10^(20)`
