Question

X-rays are produced when a target of suitable material element of high atomic mass is bombarded by a beam of fast moving and high energy particles such as:
1. neutrons
2. electrons
3. protons
4. photons

Answer 1

Correct Answer - Option 2 : electrons

X-Ray:

• X-rays are electromagnetic waves, not mechanical waves because they are diffracted by the crystal.
• X-rays are produced when a target of the suitable material element of high atomic mass is bombarded by a beam of fast-moving electrons.
• X-rays are produced due to the sudden deceleration of fast-moving electrons when they collide and interact with the target anode. In this process of deceleration, more than 99% of the electron energy is converted into heat and less than 1% of energy is converted into x-rays.
• ​X-rays ionize gases through which they pass.
• Soft X-rays have a greater wavelength and lower frequency and hard X-rays have a lower wavelength and higher frequency.
• X-rays are not deflected by electric and magnetic fields.
• X-rays show all the important properties of light rays like reflection, refraction, interference, diffraction, and polarisation, etc.
• X-rays were discovered by scientist W.C Roentgen in 1895.
• He discovered this while working with a cathode-ray tube in his laboratory.
• The frequency of X-Rays is 1016 to 1019 Hz.
• X-rays are used to detect the cracks in bones, in medicine and industries and also in security purpose
