Quantum physics is the study of the behavior of matter and energy at the molecular, atomic, nuclear, and even smaller microscopic levels. In the early 20th century, it was discovered that the laws that govern microscopic objects do not function the same in such small realms.
The quantum of light, known as a photon, is significant in physics because it helps explain the behavior of light and other electromagnetic radiation. It plays a key role in the theory of quantum mechanics, which describes the behavior of particles at the smallest scales. Understanding the quantum nature of light has led to advancements in various fields, including quantum computing and telecommunications.
In quantum physics, the behavior of particles is influenced by their mass and the presence of light. Light can affect the movement and properties of particles, leading to phenomena like wave-particle duality and quantum entanglement. The relationship between light, mass, and particle behavior is a key aspect of understanding the quantum world.

Quantum physics looks at the world of physics in terms of 'packages', or particles.Ie, gravity acts the way it does do to the behavior of the 'gravitron', which is a quantized measurement.The branch of physics that uses quantum theory to describe and predict the properties of a physical system.
Einstein founded "Einsteinian physics", which replaced Newtonian physics, but which has been superseded by quantum physics. Einstein's colleagues asked some of the questions which led to a more bizarre, quantum model of physics. Look up Schrodinger's cat for the most famous example. Einstein thought this was mystical weirdness.
If you stay outside the realms of quantum physics, then it is neither - it is a form of electromagnetic radiation.
There is unlikely to be a successor to a quantum theory of light, by the definition that the quantum theory of light is that "Light is made up of discernible particles", has very strong evidence to support it, and no alternative explanation has yet been found to explain such effects as the photoelectric effect.If you mean quantum electrodynamics, the section of the standard model of particle physics that explains light, electricity and magnetism, and therefore the standard model of particle interaction, then the only answer is that absolutely nobody knows. In fact, finding a successor to the standard model, which despite being one of the best theories ever developed is full of more holes than the titanic if taken as a theory of everything, is one of the biggest deals in all of science.One possible successor to the theory of quantum electrodynamics is the section of superstring theory that explains electromagnetism, but there are many who don't think string theory will be the answer to physics' problems, and certainly string theorists have yet to find any strong evidence supporting their theories.
Quantum physics determined that light acts like an electromagnetic wave and a particle at the same time.
Physics and chemists might collaborate on experiments involving the study of the properties and behavior of materials at the atomic and molecular levels, such as investigating the structure of nanoparticles, studying the interaction of light with molecules, or exploring the dynamics of chemical reactions using quantum mechanics principles.
No. To explain the photoelectric effect, you have to think of light as a particle, not a wave. The fact that light can be both a wave and a particle is part of quantum mechanics, not classical physics.
