Electromagnetic waves with wavelength
(i) `lambda_(1)` is used in satellite communication.
(ii) `lambda_(2)` is used to kill germs in water purifies.
(iii) `lambda_(3)` is used to detect leakage of oil in underground pipelines.
(iv) `lambda_(4)` is used to improe visibility in runways during fog and mist conditions.
Arrange these wavelengths in ascending order of their magnetude.
