Correct Answer: Sodium


Solution : The correct option is Sodium.

Yellow street lights are frequently made of high-pressure sodium (HPS) or low-pressure sodium (LPS) bulbs. This lamp emits a characteristic yellow or orange-yellow light. When energised by an electric current, sodium vapour creates a primarily yellow-orange light, which is utilised in low-pressure sodium lamps (LPS). Because of its energy efficiency and extended lifespan, sodium vapour lamp technology is a popular choice for street lighting in many places.
