Identify the electromagnetic waves whose wavelengths vary as
(a) `10^(-12)m lt lambda lt 10^(-8)m`
(b) `10^(-3)m lt lambda lt 10^(-1)m`
Write one use for each.

Explanation

(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, microwave telecommunication and microwave ovens etc.
