The Compton effect is associated with

$X$-rays are produced in an $X$-ray tube at a given accelerating voltage. The wavelength of the continuous $X$-rays will be in the range of .......

Characteristic $X$-rays are not obtained in the spectrum of a hydrogen atom because,

For continuous $X-$rays,the minimum wavelength produced is:

The potential difference applied to an $X$-ray tube is increased. As a result,in the emitted radiation

$A$ charged gold leaf electroscope has its leaves apart by a certain amount with enclosed air. When the electroscope is subjected to $X$-rays,then the leaves
