Answer:
The correct answer is- emission spectrum
Explanation:
When energy is absorbed by an atom or molecule the electron in the atom jumps into a higher energy state and when it slowly releases energy it occupies multiple energy states this shows that an electron can have multiple transitions which leads to many wavelengths that form emission spectrum.
So the range of wavelength produced or emitted by an atom which is stimulated by energy(heat or electric current) is called an emission spectrum. So here electricity is used to excite the electron present in the gas tube containing neon and when electrons emit energy it shows red color. So the correct answer is the emission spectrum.
