SUMMARY

Light is defined as electromagnetic waves that consist of alternating electric and magnetic fields, fundamentally mediated by photons. Photons are packets of energy and momentum, and there is no evidence to suggest they are composed of anything else. In contrast to thermal energy, which is associated with the kinetic energy of particles, light can be conceptualized as potential energy. The discussion emphasizes the complexity of defining "reality" in the context of physical phenomena.

PREREQUISITES
  • Understanding of electromagnetic waves
  • Familiarity with photon theory
  • Basic knowledge of energy types (kinetic vs. potential)
  • Concept of emergent phenomena in physics
NEXT STEPS
  • Research the properties of electromagnetic waves
  • Study the role of photons in quantum mechanics
  • Explore the differences between kinetic and potential energy
  • Investigate the concept of emergent phenomena in physics
USEFUL FOR

Physicists, students of physics, and anyone interested in the fundamental nature of light and energy.

Light is electric magnetic waves alternating. But are electric magnetic waves?, What are they composed of. electric and magnetic fields ? But what are they composed of ? is there any physical part of a wave to imagine. light is energy but is that the best description to what light is. We know heat is energy but we know thermal energy means atoms moving faster or slower. So what does light mean?

The best models of light is in terms of an electromagnetic interaction mediated by photons ... there is no reason to suspect that photons are made of anything else but packets of energy and momentum. Electromagnetic waves that you are probably used to are an emergent phenomenon of many photons.

In the sense that thermal energy is random kinetic energy of particles, then light is potential energy.

What something is "really" depends on how you define "real" ... if you had found what something is "really", how would you tell?
