Question

The discovery of the constant speed of light proved that classical physics was unable to explain more advanced scientific concepts and led to the birth of a new field—modern physics. The Michelson-Morley experiment proved that light moves at a constant speed at all times, regardless of the relative speed of the observer. Discuss why this characteristic makes light unique compared to all other moving objects in the universe. Support your reasoning with at least two concrete examples of other moving object

Answer 1

ANSWER:

given that a discovery of constant speed.

The constant speed of the light makes it unique which can be understood from the following examples.

Example 1

let a body A is moving with velocity "v" with respect to a body B which is at rest. Now if the body B moves with any velocity with respect to the body A, then their relative velocity becomes lesser than the previous velocity "V". Which doesn't applies to the case of the constant velocity of light. For better understanding think about two cars moving in same direction with different velocities.

Example 2

let the same situation but now the body B starts moving in the opposite direction of the body A moving with velocity "v". By doing so now the relative velocity of body A with respect to the body B is more than the previous velocity "V". But in the case of light the speed of light does not increase due to any relative velocities and is remains constant.
