When the accelerating voltage in an X-ray tube is doubled, the wavelength of the X-rays is
a. Increased to twice the original value
b. Is increased to four times the original value
c. Decreased to one-half the original value
d. Decreased to one-forth its original value
Explain
Homework Answers
Solution:
Using conservation of energy
=> e V = hc/wavelength
We can say voltage is inversely dependent on wavelength
=> wavelength = K/V where k is a constant
=> when V is doubled wavelength will decrease by one half
Option c is right
