Electrons are accelerated in television tubes through potential differences ofabout 10 kV. The highest frequency of the electromagnetic waves emitted when these electrons strike the screen ofthe tube is :

Electrons are accelerated in television tubes through potential difference of about 10 KV. (1) The lowest wavelength of the emitted X-rays is 12.4 overset(@)A . (2) The lowest wavelength of the emitted X-rays is 1.24 overset(@)A (3) The highest frequency of the emitted X-rays is 2.4xx10^(8)Hz (4) The higher frequency of the emitted X-rays is 2.4xx10^(18)Hz

The potential difference applied to an X-ray tube is 5kV and the current through it is 3.2 mA. Then the number of electrons striking the target per second is

In an old-fashioned television set, electrons are accelerated through a potential difference of 25.0 kV. What is the de Broglie wavelength of such electrons? (Relativity is not needed.)
