A source S_1 is producing, 10^15 photons per second of wavelength 5000. Another source S_2 is producing 1.02 × 10^15 photons per second of wavelength…
A source $\displaystyle S_1$ is producing, $\displaystyle 10^{15}$ photons per second of wavelength $\displaystyle 5000 \AA$. Another source $\displaystyle S_2$ is producing $\displaystyle 1.02 \times 10^{15}$ photons per second of wavelength $\displaystyle 5100 \AA$.
Then, (power of $\displaystyle S_2$ )/(power of $\displaystyle S_1$ ) is equal to :
Official answer
(2)
$\displaystyle 1.00$
