A radio transmitter operates at a frequency of `880 kHz` and a power of `10 kW`. The number of photons emitted per second are

Options

A. `1.72 xx10^(31)`
B. `1327 xx10^(34)`
C. `13.27 xx10^(34)`
D. `0.075 xx10^(-34)`

Answer

A

Explanation

No. of photons ` = ("Power")/("Energy")`
`=(10 xx10^3)/(6.6 xx10^(-34)xx880 xx10^3)=1.72 xx10^(31)`
