Electromagnetic waves with wavelength la...

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

A

`lambda_(3)gtlambda_(2)gtlambda_(4)gtlambda_(1)`

B

`lambda_(3)ltlambda_(2)ltlambda_(4)ltlambda_(1)`

C

`lambda_(3)ltlambda_(4)ltlambda_(1)ltlambda_(2)`

D

`lambda_(3)ltlambda_(2)ltlambda_(4)ltlambda_(1)`
