What is Compton effect ?
In Coolidge X-ray tube (Modern X-ray tube) how will you vary :
(1) intensity of emitted X-rays?
(2) penetrating power of emitted X-rays?

The X-ray beam coming from an X-ray tube

The X- rays beam coming from an X- rays tube will be

Increase in which of the following increases the penetrating power of the X-rays ?

In an X - rays tube , the intensity of the emitted X - rays beam is increased by

X-rays are emitted during

The metal used for making X-ray tube window is :

Explain how the intensity and penetrating power of X-ray are controlled in a Coolidge X-ray tube.

Assertion : Soft and hard X -rays differ in frequency as well as velocity. Reason : The penetrating power of hard X - rays is more than the penetrating power of soft X -rays.

A: If vacuum is not created inside an X -ray tube, X-rays will not be produced. R: Without vacuum inside the X-ray tube the electrons are not emitted by the filament.

Hydrogen atom does not emit X-rays because
