Questions
When a beam of accelerated electrons hits a target, a continuous X-ray spectrum is emitted from the target. Which of the following wavelength is absent in the X-ray spectrum, if the X-ray tube is operating at 40.000 volts?
detailed solution
Correct option is A
λmin=1237540,000=0.30Å. Hence wavelength less than 0.30Å is not possible.Talk to our academic expert!
