Scientists use telescopes to make distant objects appear closer. Some parts of a telescope are shown here. Which of the following best describes how the objective lens of this telescope helps a scientist observe the moon? (5.6C)

• The objective lens produces light.

• The objective lens blocks light.

• The objective lens reflects light.

• The objective lens refracts light.

In 1859, Henry Bursill published a book of hand shadows. The picture shows one of these hand shadows. Which property of light makes it possible to produce hand shadows? (5.6C)

• Light can be refracted.

• Light is a form of energy.

• Light travels in straight lines.

• Light can be separated into different colors.

A teacher takes the top and a side off a box. She cuts a hole in another side and puts a candle outside the box, as shown below. When the teacher lights the candle in a dark room, some of the candlelight shines through the hole. Which diagram best shows how the light appears on the opposite wall of the box? (5.6C)

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

The picture shows an area of Yosemite National Park. Which statement about light is supported by this picture? (5.6C)

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

• Light can refract in air and in clean water.

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

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