Answer» Solution :(i) In satellite communication microwaves are used so `lambda_(1)` is WAVELENGTH of microwave. (ii) Ultraviolet radiation are used to kill germs in water PURIFIER so `lambda_(2)` is wavelength of UV rays. (iii) X - rays are used to detect leakage of oil in underground PIPELINES so `lambda_(3)` is X - rays. (iv) Infrared rays are used to improve visiblity on runways during fog and mist condition so `lambda_(4)` is infrared rays. |
