What happens to light as it enters a medium with a higher refractive index?

Back

Light bends toward the normal.

FLASHCARD QUESTION

Front

What is the refractive index of a medium?

Back

The refractive index is a measure of how much light slows down in a medium compared to its speed in a vacuum.

3.

FLASHCARD QUESTION

Front

What is the formula for calculating the refractive index (n)?

Back

n = c/v, where c is the speed of light in a vacuum and v is the speed of light in the medium.

FLASHCARD QUESTION

Front

When light passes from a medium with a lower refractive index to one with a higher refractive index, how does it behave?

Back

It bends toward the normal.

FLASHCARD QUESTION

Front

What is the refractive index of a vacuum?

Back

The refractive index of a vacuum is 1.

6.

FLASHCARD QUESTION

Front

If the speed of light in a medium is greater than in a vacuum, what can be said about its refractive index?

Back

The refractive index is less than 1.

7.

FLASHCARD QUESTION

Front

What does a higher refractive index indicate about a medium?

Back
