Question
Mark the correct option of source which is associated with a line emission spectrum:
✓

Answer

  1. Neon street sign
Explanation:
Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases.
Neon lights are a type of cold cathode gas-discharge light.
Hence neon street sign are associated with line emission spectrum.
