Verified step by step guidance1
Understand the question is asking for the term that describes the smallest packet of electromagnetic energy that can be absorbed or emitted.
Recall that electromagnetic energy is quantized, meaning it comes in discrete packets rather than continuous amounts.
Know that a 'photon' is the fundamental particle or quantum of light and electromagnetic radiation, representing the smallest packet of energy.
Differentiate between the terms: 'wavelength' refers to the distance between wave peaks, 'quantum' refers to the discrete amount of energy but is a more general term, and 'electron' is a subatomic particle, not a packet of electromagnetic energy.
Conclude that the correct term for the smallest packet of electromagnetic energy is 'photon'.
