Question

A source S1 is producing, 1015 photons per second of wavelength 5000 . Another source S2 is producing 1.2 &#215; 1015 photons per second of wavelength 5100 . Then,(power of S2)/(power of S1) is equal to

Accepted Answer

For a source S1 Wavelength, &#955;1 = 5000 Number of photons emitted per second, N1 = 1015 Energy of each photon, E1 = Power of source S1, P1 = E1N1 For a source S2 Wavelength, &#955;2 = 5100 Number of photons emitted per second, N2 = 1.02 &#215; 1015 Energy of each photon, E2 = Power of source S2, P2 = E2N2 &#8756;
