From source of power 4 kW,radiation emitted are such that photon are emitted at rate of `10^(20)` photon/sec.This radiation will be in …..region of electromagnetic waves…
`[]h=6.6xx10^(-34)Js`

A

gamma rays

B

X-rays

C

ultraviolet rays

D

microwaves

Text Solution

Verified by Experts

The correct Answer is:
B
`P=(E_(n))/(t)=(nhf)/(t)=((n)/(t))hf`
`therefore f=(p)/((n)/(t)h)=(4000)/(10^(20)xx6.6xx10^(-34))`
`=6.06xx10^(16)Hz`
The spectrum containing frequency are of X-region.
