Question

If the coefficient ranges from -1.00 to 1.00, what is the strongest negative relationship?

A)- 10
B) 1.00
C) - 99
D) -1.00

Answer 1

c) It can be equal to 1.00 but it can also be greater than 1.00. It is never less than 1.00.

Step-by-step explanation:

Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.

Or ,

n = c/v.

Since speed of the light 'v' in any medium is always be less than or equal to speed of the light in the vacuum 'c', thus, the index of refraction is always be greater than or equal to 1.0.
