Name the electromagnetic waves in the wavelength range 10 nm to `10^(-3) nm`. How are these waves generated ? Write their two uses.

Explanation

Electromagnetic waves in the wavelength range 10 nm to `10^(-3)` nm `(or 10^(-8) m" to "10^(-12) m)` are known as X-rays.
X-rays are generated in an X-ray tube when electrons emitted by the cathode plate of X-ray tube after gaining high energy are bombarded on the target plate of tube.
X-rays are used (i) as a diagnostic tool in medical field, (ii) in scientific research to study atomic structure and crystal structure, (ii) in industry and by custom department for anti-smuggling operations.
