If a source of power 4 kW produces 1020 photons/second, the radiation belongs to a part of the spectrum called
As we learnt in
Energy of a photon -
If wavelength of photon is & n is the number of photon emitted per second then
This wavelength represent X-rays hence correct answer is option 2.
This is an incorrect option.
This is the correct option.
This wavelength represent X-rays hence correct answer is 2
