Define the following terms: a) Inertia b) Refractive Index
Answers
Answer:
Inertia is defined as
The phenomenon in which an object tends to retain its previous action
(for example an object at rest tends to stay ay rest while an object in motion tends to stay in motion)
Refractive index of an object is the speed of light in the second object compared to speed of light in the first object, or simply sin of angle of incidence/ angle of refraction
Answer:
Inertia: It is the property of a object to resist any change in its state of motion or rest, including changes to its speed and direction. It is the tendency of objects to keep moving in a straight line at constant velocity unless disturbed by any external force.
Refractive index: It is defined as the bending of light rays while the light ray enters from one medium to another.
