If a source of electromagnetic radiation having power 15 kW produces 10 16 photons per second, the radiation belongs to a part of spectrum is : (Take Planck constant h = 6 × 10 - 34 J s )

Step-by-step solution

As energy of one photon is given by E = Power Photon   frequency Or, E = h ν = 15 × 10 3   10 16 So, frequency of ray is ν = 15 × 10 - 13 6 × 10 - 34 = 2 . 5 × 10 21   Hz . Thus, the radiation belongs to gamma rays.
