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 tongs appears to break as the tongs enter the water. Which property of light are the students observing in this situation?

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

• 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.

A student conducts an investigation by shining a flashlight towards a flat mirror. The student changes the angle of the mirror and observes the path of the reflected light. As the mirror changes direction, the light reaching the mirror can reach the ceiling because the light-

• travels in straight lines and reflects from the surface of the mirror.

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

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

• travels through air and does not change its direction in the air.
