The intensity of X-rays from a coolidge ...

The intensity of X-rays from a coolidge tube is plotted against wavelength as shown in figure. The minimum wavelength found is `lambda_c` and the wavelength of the `k_alpha` line is `lambda_k`. As the accelerating voltage is increased.

A

`(lambda_(K)-lambda_(C))`increase

B

`(lambda_(K)-lambda_(C ))`decrease

C

`lambda_(K)` increases

D

`lambda_(K)` decreases

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda_(K)` is independent of voltage (V)
`lambda_("min") prop 1/V`
`V uarr lambda_(K)` remains unchanged and `lambda_(c )` decreases
Hence , `lambda_(K) -lambda_(C ) ` will increases .
