How many photons of frequency 10^(14) Hz...

How many photons of frequency `10^(14) Hz` will make up 19.86 J of energy ?

Text Solution

Verified by Experts

Total energy emitted per second = Power x time
19।86 J =
Power ls:। Power = 19।86 W
Number of photons, `n=P/E=P/(hu)``n=3xx10^20`
`n_p=3xx10^(10)`
