Answer» Solution :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. |
