Questions and Answers

What is the primary factor that influences the speed of light in a medium such as olive oil?

The viscosity of the oil

The color of the oil

The refractive index of the oil (correct)

The temperature of the oil

Which of the following conditions is NOT necessary for total internal reflection to occur?

Light must be traveling from a denser to a rarer medium

The interfaces between the two media must be smooth

Light must be polarized (correct)

The angle of incidence must exceed the critical angle

If the refractive index of olive oil is known, how can the speed of light in that medium be calculated?

By multiplying the refractive index by the speed of sound

By taking the square root of the refractive index

By adding the refractive index to the speed of light in a vacuum

By dividing the speed of light in a vacuum by the refractive index (correct)
