X-Rays are electromagnetic waves with a high frequency (lying between UV radiation and gamma radiation on the EM spectrum) and as a result, have a very small wavelength (on the atomic level). Because of this high frequency, they carry high amounts of energy, and have a high penetrating power. X-Rays are ionising, meaning they can cause cancer in humans if exposure is high enough.
The two main types are "hard" X-Rays and "soft" X-Rays. The differences are, "ard" X-Rays have a higher frequency, lower wavelength, carry more energy and have a higher penetrating power then "soft" X-Rays. In an X-Ray machine, an aluminium filter is often used to block the "soft" X-Rays, as they are more easily absorbed by the patient and are more dangerous because of this.

The X-ray machine at the airport is primarily used to check the physical properties of the substances in your luggage, such as density and shape. It does not analyze the chemical properties of the substances.
The X-ray machine at an airport is checking the physical properties of the substances in your luggage, such as their shape, density, and structure. It is not able to assess the chemical properties of the substances.
x-ray discovered by w c roentgen in 1895. x-ray has short wavelength. It can pass through human body. It can not pass through any metal or hard object. It is harmful to human being. x-ray are made up of photons. it is more dangerous for pregnant women. x-ray travel in straight direction. wavelength of x-ray is 10-8.
X has long been used to denote an unknown quality of quantity and when X-rays where first discovered their exact nature and properties were unknown, so the name X (unknown) ray was chosen.
