#### X-Rays :-

X-Rays or X-radiation as a form of electromagnetic radiation. They are powerful waves of electromagnetic energy. Most of them have a wavelength ranging from 0.01 to 10 nanometres, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 100 eV to 100 keV.

#### Invention of the X-Ray :-

German physicist Wilhelm Rontgen is typically credited for the discovery of X-Rays in 1895 because he was the first to comprehensively study them, though he is not thought to be the first to have seen and perceived their effects.

#### Property of X-rays :-

X-ray photons carry an abundant amount of energy that is able to ionize atoms and disrupt the molecular bonds. X-ray has a shorter wavelength than that of the visible light. Hard X-rays can penetrate dense objects without getting much scattered.  The penetration depth varies according to the magnitude of the x-ray spectrum.

• They travel in a straight line and do not carry an electric charge with them.
• They are capable of travelling in a vacuum.
• They have a shorter wavelength of the electromagnetic spectrum.
• Requires high voltage to produce X-Rays.
• They are used to capture the human skeleton defects.

#### Types of X-Rays :-

• Lungs X-rays
• Abdomen X-rays
• Standard Computed Tomography
• Kidney, Ureter, and Bladder X-ray
• Teeth and bones X-rays
• Chest X-rays

#### Uses of X-Rays  :-

Since the discovery of X-radiation, they are used in various fields and for various purposes. Some key uses of X-Ray are given below.

In Industrial Purpose: It is widely used to detect the defects in the welds.

In Restoration: They are used to restoring old paintings.

In Medical Use: They are used for medical purposes to detect the breakage in human bones.

In Security: They are used as a scanner to scan the luggage of passengers in airports, rail terminals, and other places.

In Astronomy: It is emitted by celestial objects and are studied to understand the environment.
