Explanation:
Suppose the EM wave travels at light speed . A change in travel distance of the order of 3 m would result of a change in travel time of
There are two main reasons why a bouncing ball rise to a lower height with each bounce: 1) because every time it hits the ground it encounters friction, which slows it down, and every time it rises from the ground it encounters air resistance.
