Question

how does light travel from one point to other?​

Answer 1

Answer:

An important point about light is that it not only contains energy but it also contains momentum, and momentum, perforce, means motion. Think of it as two fields. There is an oscillating electric field, and as it oscillates, from Maxwell’s equations that generates an oscillating magnetic field, and because of the momentum, that is generated in front of the line of travel. That magnetic field then generates a corresponding oscillating electric field in front of it, each field drawing energy from the collapsing field behind it. (Electric and magnetic fields both contain energy, depending on the field strength.)

Answer 2

light does not require any medium for travelling.

it is the fastest known matter to man.

light exhibits both wave nature and particle nature.

it travels at the speed of approximately 3 x 10^8 m/s
