The theory that electromagnetism is made up of both energy and particles is called Quantum Electrodynamics (QED). It describes how electromagnetic interactions occur at the quantum level by combining quantum mechanics and classical electromagnetism.
branches of physics are - Neclear physics Electromagnetism Quantum mechanics Interdisciplinary fields Quantum field theory
Studying electromagnetism is crucial because it helps us understand the fundamental forces at play in the universe. It has led to the development of technologies like electric power generation, motors, and communication devices. Additionally, electromagnetism forms the basis of many other branches of physics, such as optics and quantum mechanics.

The six divisions of physics are classical mechanics, thermodynamics and statistical mechanics, electromagnetism, quantum mechanics, relativity, and astrophysics/cosmology. These branches cover the study of various natural phenomena and form the foundation of our understanding of the physical world.

No, electromagnetism does not prevent us from falling through the floor. The repulsion between electrons in our body and the electrons in the floor creates the sensation of solidity, keeping us from passing through it.
Either as: A particle, the photon, A packet of energy, the quantum of electromagnetism(still known as the photon), and A wave of a specific frequency, a wave of radiation that has a certain energy
One medium is electromagnetism.
- classical mechanics - motion, velocity, acceleration, inertia, forces, momentum, etc. - electricity, magnetism, and light (electromagnetism) - wave mechanics - thermodynamics - quantum mechanics - quantum electrodynamics - quantum chromodynamics - superconductivity - general and special relativity - string theory and supersymmetry - cosmology (the list goes on and on)
Measurements in quantum physics are crucial as they allow us to observe and understand the behavior of quantum systems. They provide us with information about the state of a system, such as its position, momentum, or energy. Measurements also play a key role in determining the probabilities of different outcomes in quantum experiments, helping us make predictions and test the validity of quantum theory.
