Physics - EM Waves Question with Solution | TestHub

(a) uv rays - used for water purification
(b) $x$-rays have high penetration power. Therefore, they are used for diagnosing fracture
(c) Microwaves are used for mobile and radar communication
(d) Infrared waves show less scattering therefore used in foggy days

$\left(\mathrm{a}-\mathrm{ii}\right), \left(\mathrm{b}-\mathrm{i}\right), \left(\mathrm{c}-\mathrm{iii}\right), \left(\mathrm{d}-\mathrm{iv}\right)$
