If `n_(r)` and `n_(b)` are respectively, the number of photons emitted by a red bulb and a blue of equal power in a given time, then

A

`n_(r) = n_(b)`

B

`n_(r) lt n_(b)`

C

`n_(r) gt n_(b)`

D

data in insufficient

Text Solution

Verified by Experts

The correct Answer is:
C
`P_(r)=(n_(r)hc)/lambda_(r), P_(b)=(n_(b)hc)/lambda_(b)`
if `P_(r)=P_(b)` Since `lambda_(r) gt lambda_(b) implies n_(r) gt n_(b)`
