Light Reflection, Refraction and Absorbtion

A person observes a fish in a lake. The position of the fish is shown.

Which statement best explains why the observed fish appears to be closer to the surface than the actual fish.

• When light travels from water into air, the light changes directions.

• The light bounces off of the water and creates a reflected image of the fish.

• When white light passes through the surface of the water, the light separates into colors.

• the light enters the water and exits the water at the same angle.

Some students are feeding a crab in an aquarium. They use tongs to place the food directly in front of the crab.

The students look through the side of the aquarium. They notice that the image of the tongs appears to break as the tongs enter the water.

• F. Light can be refracted and separated into different colors as it moves from air to water.

• G. Light is refracted as it moves from one medium to another medium.

• Light travels in a straight line and can be reflected off the surface of water.

• Light is absorbed by water and reflected off glass.

• F. travels in a straight line and reflects from the surface of the mirror

• G. refracts in the glass of the mirror and is spread out all over the room

• H. enters the mirror and changes directions when it is refracted by the back of the mirror

• J. travels through air and does not change its directions in air.

• F. Light travels in straight lines until it enters a different material like water in a lake

• G. Light can refract in air and in clear water.

• H. The water in the lake is blue because light forms an image

• J. Light is reflected off the smooth surface of the lake.
