Modern Physics 2 Question 11

11. An electron beam is accelerated by a potential difference V to hit a metallic target to produce X-rays. It produces continuous as well as characteristic X-rays. If λmin is the smallest possible wavelength of X-rays in the spectrum, the variation of log⁡λmin with log⁡V is correctly represented in

Show Answer

Solution:

  1. λmin =hceV

log⁡(λmin)=log⁡hce−log⁡Vy=c−x
