In the context of the energy of light, what are the discrete packets of light energy called?

• A. Electrons
• B. Protons
• C. Photons
• D. Neutrons

Answer: (C)

Verified step by step guidance

1. Understand that light exhibits both wave-like and particle-like properties, a concept known as wave-particle duality.
2. Recognize that the discrete packets or quanta of light energy are called photons, which are fundamental particles of light.
3. Recall that photons carry energy proportional to the frequency of the light, described by the equation \(E = h \nu\), where \(E\) is energy, \(h\) is Planck's constant, and \(\nu\) is the frequency.
4. Note that electrons, protons, and neutrons are particles related to atoms and matter, not the discrete energy packets of light.
5. Conclude that the correct term for discrete packets of light energy is photons.
