The short-wavelength limit shifts by 26 ...

The short-wavelength limit shifts by 26 pm when the operating voltage in an X-ray tube is increased to 1.5 times the original value. What was the original value of the operating voltage?

Text Solution

Verified by Experts

The correct Answer is:
A
`26 pm = 0.26 Å`
Now, 0.26 = (12475)/(V) - (12375)/(1.5 V).
