Which of the following does not characterise X-rays?
(a) The radiation can ionise the gas
(b) It causes fluorescence effect on $\mathrm{ZnS}$
(c) Deflectéd by electric and magnetic fields
(d) Have wavelength shorter than ultraviolet rays

Key Concepts

Wavelength

Wavelength is the distance between consecutive peaks of a wave, and it is a fundamental property of any electromagnetic radiation. X-rays have wavelengths that are shorter than those of ultraviolet rays, a factor that contributes to their high penetrative power and unique interaction with matter.

Fluorescence

Fluorescence involves the absorption of energy by a material and its subsequent re-emission as light of a longer wavelength. Although not a defining property of X-rays, their interaction with certain materials can cause fluorescence, a phenomenon exploited in various scientific and industrial applications.

Electromagnetic Deflection

Electromagnetic deflection typically involves the bending of charged particles under the influence of electric or magnetic fields. Unlike charged particles, electromagnetic waves such as X-rays are neutral, meaning they are not deflected by these fields. This property helps distinguish X-rays from other types of radiation with particle characteristics.

Electromagnetic Radiation

Electromagnetic radiation refers to energy propagating through space in the form of oscillating electric and magnetic fields. X-rays are a type of electromagnetic radiation characterized by high energy, high frequency, and short wavelengths, which distinguishes them from other forms like radio waves or visible light.

Ionization

Ionization is the process by which atoms or molecules gain or lose electrons, becoming charged in the process. X-rays have enough energy to ionize gases and other materials, which is a key characteristic that underlies many of their applications in medical imaging and material analysis.
