Question

Why light travels between two points in the quickest path?

Answer 1

Answer:

Explanation:

because The shortest distance between two points is the length of line joining the two points straight. Normally light travels straight but it has a property to bend at corners of objects.

Gravity can also create disturbance in path of light.

So, as long as light travels straight without any distractions.
