Answer:
The principle of least time: Light always takes the quickest path between any two points (which may not be the shortest path).
The principle of least time: Light always takes the quickest path between any two points (which may not be the shortest path).Rectilinear propagation of light and the law of reflection [∠i=∠r] can be validated by Fermat’s principle of least time.

Answer:
The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro's law).
