Light is a form of energy.
this would be the emission and absorption lines in the light spectrum. certain elements absorb or emit wave lengths of light that is unique to that element. by studying the "rainbow" of the star astronomers can determine its properties and elements by looking at which wave lengths of light are absorbed or emitted.
Fire emits light in the form of heat and visible light, but it does not reflect light like a mirror or a shiny object would. The light emitted by fire comes from the combustion of fuel and can be influenced by the temperature and type of material burning.
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
No. That would violate the laws of physics.
No, a torch light is not a luminous object. The light emitted by the torch is produced by the conversion of electrical energy to light energy, rather than emitting light through its own chemical reactions like a luminous object would.
Physics would probably be the most obvious choice.

Chemistry and physics
Quantum leaps between energy levels that are farther apart would be associated with the greatest energy of emitted light. This is because energy and wavelength of emitted light are inversely proportional, so larger energy differences result in shorter wavelength (higher energy) light being emitted.

G40 is a supernova remnant. Particle physics is the study particles, radiation and matter. One would be able to study the properties of the G40 by applying the principles of particle physics

First chemistry; after physics and mathematics.

well there is no specific study. that would be the detective but the tools they yous would be physics.
