With the switches in these positions, which lights are on?

• All the lights

• Lights 1 and 2 only

• Lights 3 and 4 only

• None of the lights

In some circuits that are used for decorating, one burned-out lightbulb will prevent all the other lightbulbs from lighting. In other circuits, one burned-out lightbulb will have no effect on the other lightbulbs.

In which of these circuits will the other lightbulbs still light even if one bulb is burned out?

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 a the tongs enter the water. Which property of light are the students observing in this situation?

• 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 the 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 cab 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 air.

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

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

• Light can refract in air and in clear water.

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

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