This is a real picture of a polar taken at a zoo. Fortunately for the polar bear, its head is actually connected to its body. Why does it look like the head is separate from the body?

• Light waves are bouncing as they pass from air to water.

• Light waves are not passing from the air to the water.

• Light waves are traveling in a straight line as they pass from air to water.

• Light waves are bending as they pass from air to water.
