Explanation:
Answer:
gases Z and Y.
Explanation:
Photons are emitted when electrons jump from a higher energy level to lower energy level and these photons carry light energy.
The light emitted at various wavelengths produce emission spectrum, when viewed via a spectroscope.
While analyzing the image, we could see that the spectrum of unknown sample contains the gases Z and Y.
