What do you mean you need to be more specific
Answer:
Wave theory of light explains the phenomena of interference, diffraction, scattering, dispersion, polarisation etc. Complete solution: Around 1700, it was concluded by Newton that light was a group of particles. It was called corpuscular theory.
No the only thing that affects it is how it is built
If the objects comprise a gas, then the first object contains more
thermal energy (heat) than the second object.
If the objects are solid, then you can't draw any conclusion unless
both objects have the same total mass. If that's the case, then the
first object must be moving faster than the second one.
I think it might be a or d i hope i have helped :)
