In one joule of energy, the number of photons with have number equal to x is

A

`(hcx)^(-1)`

B

`x(hc)^(-1)`

C

hcx

D

`hc(x)^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`E = n. hv = n.h (c)/(lambda) n.hc bar(v)` or `n = (E)/(hc bar(v))`
Now, `E = 1, bar(v) = x :. N = (1)/(hcx)` or `(hc x)^(-1)`.
