Question

In a Coolidge tube, X-rays are produced when:
Options
A Electrons are accelerated from the anode to the cathode.
B Fast moving electrons are suddenly stopped by a solid target.
Correct Answer
C Protons are bombarded onto a heavy nucleus.
D Alpha particles scatter off a gold foil.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text states: 'X-rays are produced when fast moving electrons are suddenly stopped by a solid target.' This occurs when thermionic electrons emitted from a heated filament are accelerated towards a target (anode) in the Coolidge tube.

Hint

Think about the primary mechanism of X-ray generation described for the Coolidge tube, involving electron interaction with a target.
