Find the
(a) maximum frequency, and
(b) minimum wavelength of X-rays produced by 30kV electrons.

Text Solution

Verified by Experts

Here the accelerating voltage `V=30kV=30xx10^(3)V`
(a) Maximum frequency of X-rays produced
`v_(max)=(E)/(h)=(eV)/(h)=(1.6xx10^(-19)xx30xx10^(3)J)/(6.63xx10^(-34)J)=7.24xx10^(18)Hz`
(b) The minimum wavelength of X-rays produced
`lamda_("min")=(c)/(v_(max))=(3xx10^(8))/(7.24xx10^(18))=4.1xx10^(-11)m=0.041nm`.
