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?

•

What does the picture demonstrate about light?

• Light travels in straight lines.

• Light cannot reflect from more than one surface.

• Light can curve through objects.

• Light can curve around objects.

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.
