1. X-rays are produced when:

 A) Electrons from the anode strike the cathode target

 B) Electrons from the cathode strike the anode target

 C) Photons from the cathode strike the anode target

 D) Protons from the anode strike the cathode target

Correct Answer: B

Rationale: X-rays are produced when high-speed electrons from

the cathode filament strike the anode target. Two types of

interactions occur: characteristic and bremsstrahlung .

,2. What is the smallest particle of an element called?

 A) Electron

 B) Photon

 C) Atom

 D) Proton

Correct Answer: C

Rationale: The atom is the smallest particle of an element that

retains the properties of that element. Atoms consist of protons,

neutrons, and electrons .




3. X-rays travel as a bundle of energy called:

 A) Electrons

 B) Photons

 C) Protons


2

,  D) Neutrons

Correct Answer: B

Rationale: Photons are discrete bundles of electromagnetic

energy. X-ray photons have no mass or charge but travel at the

speed of light .




4. The height of a wave is called:

 A) Frequency

 B) Wavelength

 C) Amplitude

 D) Velocity

Correct Answer: C

Rationale: Amplitude represents the height of the wave from the

baseline to the peak. Greater amplitude indicates higher

intensity .

, 5. The number of X-ray waves passing a given point per unit

time is called:

 A) Amplitude

 B) Wavelength

 C) Frequency

 D) Velocity

Correct Answer: C

Rationale: Frequency is measured in hertz (Hz) and determines

the energy of the photon. Higher frequency = higher energy .
