X-rays ProductionEasyQuestion 20189

Question

X-rays are produced when:

A
Infrared light is reflected
B
High-energy electrons are suddenly decelerated (Bremsstrahlung) or cause inner-shell transitions
Correct
C
Radio waves are amplified
D
Atoms are cooled to low temperatures

Correct answer

High-energy electrons are suddenly decelerated (Bremsstrahlung) or cause inner-shell transitions

Explanation

X-rays (λ: 0.01–10 nm) arise from Bremsstrahlung (braking radiation when fast electrons decelerate in a target) or characteristic X-rays from inner electron shell transitions in heavy atoms.
