Nuclear Physics and RadioactivityHard
Question
Let nr and nb be respectively the number of photons emitted by a red bulb and a blue bulb of equal power in a given time
Options
A.nr = nb
B.nr < nb
C.nr > nb
D.Data insufficient
Solution
Pr = 
, Pb = 
if Pr = Pb Since λr > λb ⇒ nr > nb.
, Pb = if Pr = Pb Since λr > λb ⇒ nr > nb.
