Students place a toy elephant on the floor in a room without windows. The students turn the room’s light on and off and record their observations in the table.

Which statement describes the conditions that allow the students to see the toy?

• Light rays reflect off the toy car and travel to the lamp.

• Light rays reflect off the toy car and travel to the students' eyes.

• Light rays refract off the toy car and travel to the lamp.

• Light rays refract off the toy car and travel to the students' eyes.

Elijah is standing on the shore of a lake and sees a fish in the water. The fish appears to be closer to the surface than it actually is. 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 direction.

• The light bounces off 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.

• Arrow Y and Arrow Z show light refracting as it interacts with the surface.

• Arrow X and Arrow Z show light reflecting as it interacts with the surface.

• Arrow W and Arrow Y show light reflecting as it interacts with the surface.
