Answer» Solution :(a) ELECTROMAGNETIC waves of wavelengths range `10^(-12)m lt LAMBDA lt 10^(-8)m` are kwon as X - rays. These are used as diagnostic tool in medicine, for scientific research and crystallography. (B) Electromagnetic waves of wavelengths `10^(-3) lt lambda lt 10^(-1)m` are the microwaves which are used in radar, microwavetelecommunication and MICROWAVE ovens etc. |
