Emission

The video tutorial explains the emission of light from atoms or molecules, which occurs when electrons transition from an excited state to a lower energy state. This process is fundamental in understanding how light is produced at the atomic level.

What is emitted from an atom or molecule during the process of light emission?

• Sound

• Heat

• Light

• Electricity

What triggers the emission of light in atoms or molecules?

• Atoms splitting

• Electrons gaining energy

• Molecules combining

• Electrons dropping to a lower energy state

In the context of light emission, what happens when electrons are in an excited state?

• They remain stable

• They absorb light

• They emit sound

• They drop to a lower energy state

What is the final state of electrons after they emit light?

• Excited state

• Lower energy state

• Neutral state

• Higher energy state

Which of the following is NOT a result of electrons transitioning to a lower energy state?

• Release of energy

• Stability of the atom

• Absorption of light

• Emission of light
