When the number of electrons striking the anode of an x-ray tube is increased, the of emitted X-Rays increases.

1. density

2. frequency

When the number of electrons striking the anode of an x-ray tube is increased, the density of emitted X-Rays increases.

Option: 1

Explanation:

As the electron speed increases, the heat radiation also increases from thermionic emission, which causes more heat and more X-ray release. X-rays are produced by an a vacuum tube called X-ray tube that uses more voltage to make the electrons accelerate which the hot cathode releases to a high velocity.

This high speed electrons meets in a collision with a metal target which is the anode, and thus create the X-rays. So, the electron number available and the time period set for their release from the filament determines how many x-rays are produced from the anode. Hence, more the number of electrons striking the anode,the more is the emission of x-rays.
