Question
Write a short note on X-rays.
✓

Answer

→The region of electro magnetic spectrum beyond the UV region is called X-ray region.
→Range of wave length: 10-8m(10 nm) to 1013m ($10^{-4}nm$).
→X-rays can be generated by bombarding a metal target by high energy electrons.
→X-rays are used as a diagnostic tool in medicine and as a treatment for certain forms of cancer.
→Because X-rays damage (or destroy) living tissues and organisms, care must be taken to avoid unnecessary or over exposure.
