`n_(R)` and `n_(g)` give the number of photons in red and green beams of light. If the two beams have the same energy, then

A

`n_(R) lt n_(g)`

B

`n_(R) gt n_(g)`

C

`n_(R) = n_(g)`

D

`n_(R)=0.75n_(g)`

Text Solution

Verified by Experts

The correct Answer is:
B
`E_(R)=E_(g)` and `:'E=hv`
`:.n_(R)hv_(R)=n_(g)hv_(g)`
`:.(n_(R))/(n_(g))=(v_(g))/(v_(R))` but `v_(g) gt v_(R) :.n_(R) gt n_(g)`
