The energy of photon of light having frequency of `3 xx 10^(15)S^(-1)` is

Text Solution

Verified by Experts

The energy of photon is given by
`E = hv`
where frequecy of the light , `v = 3.0 xx 10^15) s^(-1)`
Plank.s constant, `h = 6.63 xx 10^(-34) Js`
`E = (6.63 xx 10^(-34) J s)`
`xx (3.0 xx 10^15 s^(-1))`
`= 6.63 xx 3 xx 10^(-19) J`
`= 1.99 xx 10^(-18) J`
