Answer:
The refractive index of the outer coating is 1.52.
Explanation:
Refractive index of interior part, n' = 1.97
critical angle, C = 50.4°
Let the refractive index of the coating is n.
Use the Snell's law,
Answer:
The Spring force
Explanation:
The Spring force is a force that is centered around, guess what, springs. Al that the Spring force says is that when a spring is compressed or stretched out, it will return to the state that it was originally in, and because it is retracting it falls under the Spring force.
