Question
A green bulb and a red bulb are emitting the radiations with equal power. The correct relation between numbers of photons emitted by the bulbs per second is
Options
A.ng = nr
B.ng < nr
C.ng > nr
D.unpredictable
Solution
$E_{g} = E_{r} \Rightarrow n_{g}.\frac{hc}{\lambda_{g}} = n_{r}.\frac{hc}{\lambda_{r}} \Rightarrow \frac{n_{g}}{n_{r}} = \frac{\lambda_{g}}{\lambda_{r}} < 1$
