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.

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.
