A transmitter of power 10 kW emits radio waves of wavelength 500 m . The number of photons emitted per second by the transmitter is of the order of

Options

  1. A10³⁷
  2. B10³¹
  3. C10²⁵
  4. D10⁴³

Correct answer

B. 10³¹

Step-by-step solution

Power, P= n h c t Number of photons emitted per second, aligned & n t = hc = (10 10^3 ) (500 10¹⁰ ~A ^ ) (12375 1.6 10⁻¹⁹ ~J - A ^ ) & =2.52 10³¹ aligned It is of the order of 10³¹ .
