A source `S_(1)` is producing `10^(15)` photons/s of wavelength `5000 Å` Another source `S_(2)` is producing `1.02 xx 10^(15)` photons per second of wavelength `5100 Å`. Then `("power of" `S_(2))/("power of" S_(1))` is equal to

Options

A. `0.98`
B. `1.00`
C. `1.02`
D. `1.04`

Answer

B

Explanation

`("Power of" S_2)/("Power of" S_1)=(n_2((hc)/lamda_2))/(n_1((hc)/lamda_1))=(n_2lamda_1)/(n_1lamda_2)=1`
