What statement correctly identifies the reason for the appearance of the girl's eye through the magnifying glass?

• The light is refracted through the lens and makes her eye bigger.

• The light is reflected through the lens and makes her eye bigger.

• The light is refracted through the lens and makes her eye smaller.

• The light is reflected through the lens and makes her eye smaller.

Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.
• The light rays that travel through water and then into air are enlarged.
• The light rays that travel through air and then into water are reflected.
• The light rays that travel through air and then into water are reduced.

A student placed a pencil in a cup of water.  The pencil appears broken because light-

• always travels in a straight line
• bends when it passes through water
• makes the water in the glass evaporate
• reflects the pencil on the water's surface

Scientist use telescopes to make distant objects appear closer. Some parts of a telescope are shown above. Which of the following best describes how the objective lens of this telescope helps a scientist observe a moon?

• The objective lens produces light

• The objective lens blocks light

• The objective lens reflects light

• The objective lens refracts light

The picture shows a child standing in a swimming pool. Why does the lower part of the child appear so much different in size from the upper part? (5.6C)

• The light rays that travel through water and then into air are refracted.

• The light rays that travel through water and then into air are enlarged.

• The light rays that travel through air and then into water are reflected.

• The light rays that travel through air and then into water are reduced.

Some students paint the inside of several boxes. They paint each box a different color. They observe that the inside of the box painted white looks brighter than the others. What is the most likely reason this box looks brighter? (5.6C)

• More light is reflected off white paint.

• More light is refracted by white paint.

• More light passes through white paint.

• More light is absorbed by white paint.

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. Which property of light are the students observing in this situation? (5.6C)

• Light can be refracted and separated into 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 toward 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---(5.6C)

• 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 air
