`X`-rays are produced by accelerating electrons by voltage `V` and let they strike a metal of atomic number `Z` . The highest frequency of `X - rays` produced is proportional to

A

`V`

B

`Z`

C

`(Z - 1)`

D

`(Z - 1)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Mosley's law `v prop (Z - b)^(2)`
For `k_(alpha)` line, `b = 1`, and it has maximum frequency so `v_(max) prop (Z - 1)^(2)`
