If the potential difference of coolidge ...

If the potential difference of coolidge tube probucing X-ray is increased, then choose the corrent option (s).
Here, `lambda_0` is cut off wavelength and `lambda_(Ka) and lambda_(K beta)` are wavelengths of `K_(alpha) and K_(beta)` characteristic X-rays.

A

the interval between `lambda_(Kalpha)` and `lambda_(Kbeta) ` increases

B

the interval between `lambda_(Kalpha)` and `lambda_0 ` increases

C

the interval between `lambda_(Kbeta)` and `lambda_0 ` increases

D

`lambda_0` does not change

Text Solution

Verified by Experts

The correct Answer is:
B, C
`lambda_(K_alpha)` and `lambda_(K_beta)` will remain unchanged, But `lambda_0` will
decrease `(as lambda_0 prop (1)/(V)).`
`:.Deltalambda_1 = lambda_(K_alpha) - lambda_0 or Delta lambda_2 = lambda_(K_beta) - lambda_0`
will increase.
