Understanding Apparent Depth and Refraction

What happens to light when it travels from one medium to another with a different refractive index?

• It bends towards the normal.

• It bends away from the normal.

• It stops completely.

• It travels in a straight line.

When viewed from above, how does the depth of an object in water appear due to refraction?

• Deeper than it actually is.

• Shallower than it actually is.

• Invisible.

• At the same depth as it actually is.

What is the index of refraction for air typically considered to be?

• 1.5

• 0.75

• 1

• 1.33

In the example provided, what is the actual depth of the fish in the lake?

• 2.25 meters

• 3.0 meters

• 1.5 meters

• 4.0 meters

How is the apparent depth of the fish calculated using the indices of refraction?

• By dividing the actual depth by the ratio of the indices of refraction.

• By adding the indices of refraction.

• By subtracting the indices of refraction.

• By multiplying the actual depth by the ratio of the indices of refraction.
