The ratio of the power of a light source $\displaystyle S_1$ to that the light source $\displaystyle S_2$ is $\displaystyle 2$ . $\displaystyle S_1$ is emitting $\displaystyle 2 \times 10^{15}$ photons per second at $\displaystyle 600$ nm . If the wavelength of the source $\displaystyle \mathrm{S}_2$ is $\displaystyle 300$ nm , then the number of photons per second emitted by $\displaystyle \mathrm{S}_2$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{14}$.
