Emisión (física)

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 described?

• Electricity

• Sound

• Light

• Heat

What happens to electrons during the transition process?

• They gain energy and move to a higher state.

• They lose energy and move to a lower state.

• They disappear completely.

• They remain in the same state.

Which state do electrons move from during the transition?

• Stable state

• Ground state

• Excited state

• Neutral state

What is the result of electrons moving to a lower-energy state?

• Absorption of sound

• Absorption of light

• Emission of light

• Emission of sound

Which of the following is NOT involved in the process described?

• Atoms

• Molecules

• Protons

• Electrons
