PHY 104 Atomic Structures Objective Question

Question

What is the primary mechanism described for X-ray production when fast-moving electrons are suddenly stopped by a solid target in a Coolidge tube?
Options
A Atomic transitions between discrete energy levels.
B Bremsstrahlung (braking radiation).
Correct Answer
C Radioactive decay of atomic nuclei.
D Electron capture.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text explains: 'X-ray can be categorized as either Bremsstrahlung or Characteristic. When electrons hit the anode, they decelerate or brake and emit Bremsstrahlung (meaning braking radiation in German) x-rays.' It also notes Bremsstrahlung is produced in a Coolidge tube.

Hint

The name of this type of radiation translates to 'braking radiation' in German.
