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.

What branch of physics that study about light?
Variously: physics, optics, quantum mechanics, etc.
Define the major division and subdivision of physics?
Classical physics and (Quantum or modern) Physics Mechanics Thermodynamics Sound Light Optics Magnetism Electricity
What theory of light best explains the emission of electromagnetic radiation of an excited atom?
Quantum Mechanics
Is light a gas or a mass?
If you stay outside the realms of quantum physics, then it is neither - it is a form of electromagnetic radiation.
Can classical physics explain the photoelectric effect?
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.
What will be the theory after the quantum theory of light?
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.
Why will gravity alter the path of light if light itself does not have any mass?
Quantum physics determined that light acts like an electromagnetic wave and a particle at the same time.
Is light matter?
No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) as well as waves by quantum physics.
What are the subdivisions of physics and its description?
Mainly:Mechanics (Newtonian & relativistic): - mater - time - space;Molecular physics & thermodynamics: - physics of thermal movement;Electromagnetism: - physics of E,H - field;Wave motion: - physics of sound, light, ..., solitons (tsunami);Quantum physics: physics of micro-world;High energy physics.
Is light has fastest speed?
If by the "Light" you mean stream of photons as far as science knows than: Yes! Except in quantum physics in some hypothetical theories!
Could you solidify light and use a more dense form to push the other light therefore moving at light speed?
No. If light were to become a solid it would cease to be light. What about the quantum method in physics concerning light.
What is a principle of light?
The main principle of light in quantum physics is its duality. That by certain ways of measuring it it is a wave. Then by means of measuring its' physical properties it is a particle. Go Figure.
