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

`E=nh_(v)`, where hv is the energy of a photon in a radiation of frequency v and n is the number of photons in the radiation.
`therefore n=E/(hv) = 6.63/((6.63 xx 10^(-34))(10^(14))) = 10^(20)`
