Question

An electromagnetic wave has a wavelength of 70 Å. Name the wave and state its source and uses.

Answer 1

Name of the Wave: X-rays (specifically, soft X-rays).

Source: They are produced when high-energy electrons rapidly decelerate or strike a metal target of a high atomic number (such as tungsten) inside an X-ray tube.

Common Uses: They are widely used in medicine to detect bone fractures or dental cavities and in security scanners at airports to check luggage.
