Consider two light sources of wavelengths $ \lambda_1\: and\: \lambda_2 (\lambda_1 > \lambda_2)$ which are emitting $n_1\: and \: n_2$ photons respectively, in a given time. Assume equal power for both sources, then

Question

$\begin {array} {1 1} (a)\;n_1 > n_2 & \quad (b)\;n_1 < n_2 \\ (c)\;n_1 = n_2 & \quad (d)\;Can’t\: be\: determined \end {array}$
