The energy of the electromagetic wave is of the order of `15` keV. To which part of the spectrum dose it belong?

A

`gamma`-rays

B

`X`-rays

C

Infrared rays

D

Ultraviolet rays

Text Solution

Verified by Experts

The correct Answer is:
B
`E=15` ke V
`lambda =(hc)/(E)=(6.6xx10^(-19)xx3xx10^(8))/(15xx10^(6)xx1.6xx10^(-19))`
`lambda=0.8Å ~~1Å`
