X-ray Physics Quiz

Which type of X-rays is emitted from higher atomic number elements and has higher energy?

• Bremsstrahlung X-rays

• Soft X-rays

Who discovered X-rays on 8th November 1895?

• Mihran Kassabian

• Elihu Thomson

• Thomas Edison

• Wilhelm Conrad Roentgen

What is the main reason for the reduction in relative intensity after the highest point in the Bremsstrahlung X-rays spectrum?

• Less nearby electrons passing the nucleus target

• Decrease in photon energy

• Increase in wavelength of the X-rays

• Absorption of the photons in the anode target

What is the term used to refer to a radiographic image produced using X-rays?

• X-ray vision

• Radiation image

• X-ray photograph

• X-ray

Which type of radiation interaction with matter is responsible for the emission of electrons when light hits a material?

• Photoelectric effect

• Compton scattering

• Pair production

• Bremsstrahlung

What is the main function of contrast agents in X-ray imaging?

• To block the X-rays from reaching the film

What is the main reason for the occurrence of line spectrum or characteristic X-rays?

• Emission of electrons when light hits a material

• Energy of accelerated electron higher than energy binding of electron in inner shell

• Absorption of the photons in the anode target
