Question

An X-rays tube is applied at 100000V. Calculate the Maximum frequency and minimum wavelength of X- rays?

Answer 1

Answer:

Explanation:

If electrons are accelerated to a velocity v by a potential difference V and then allowed to collide with a metal target, the maximum frequency of the X-rays emitted is given by the equation:
