The inert gas used as beacon light is - (1) Kr (2) Ar (3) He (4) Ne

The inert gas used as beacon light is - (1) Kr (2) Ar (3) He (4) Ne
by

1 Answer

Answer :

(4) Ne Explanation: Neon is used in neon discharge lamps and advertising signs because the neon lights are visible from long distances. Since the light of neon signs has a better penetrating power through fog and mist, the neon signs are also used in beacon lights for the safety of air and sea navigation.
