Physics Question from JEE Main 2025 · 24 January, Shift 2

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