Circuits and Light Quiz

A student designed the circuit above. Which switches should the student close to produce sound energy only?

• Switch 1 and 3

• Switch 1, 2, and 3

• Switch 1 and 4

• Switch 2 and 3

A student designed the circuit above. What would most likely happen if the student closed Switch 1, Switch 2, and Switch 4?

• Bulb A would light up and the bell would ring, but bulb B would not light up.

• Bulb B would light up, but bulb A would not light up and the bell would not ring.

• Neither of the bulbs would light up, and the bell would not ring.

• Both of the bulbs would light up, but the bell would not ring.

A student observes a hotplate on a table. The hotplate has an on / off switch and a dial to control the temperature. The hotplate is not in use now, but will be used in the science class investigation on electrical circuits.

In order to use the hotplate during a science investigation, what must the student do to the hotplate to complete the circuit?

• Plug the hotplate into the outlet.

• Turn the switch to the "on" position.

• Plug in the hotplate, and place a beaker on the plate.

• Plug in the hotplate, and turn the switch to the "on" position.

A student designed the circuit below. The ball is on, and both bulbs are lit. What could the student do to turn the bell off but keep the bulbs lit?

• Remove wire 1 only

• Remove wire 3 and wire 5

• Remove wire 2 only

• Remove wire 1 and wire 3

Observe the circuit above. Which procedure can a student use to turn on the green and red lights only?

• The student cannot follow any procedure to turn on the green and red lights only.

• The student can close switch A and switch C, but leave switch B open.

• The student can close switch A and switch B, but leave switch C open.

• The student can close switch B and switch C, but leave switch A open.

Observe the image above. After reflecting off of the mirror, which object will the light coming from the laser most likely strike next?

• The marble

• The apple

• The rock

• The laser

Students were asked to investigate the behavior of light. Students were given a candle and a piece of cardboard with a hole in it. Students placed the cardboard between the candle and the wall and observed the location of the image on the wall. Which property of light causes the image of the candlelight to appear near the bottom of the wall?

• Light refracts when it travels through a new medium.

• Light reflects off of objects at a complementary angle.

• Light travels in a straight line until it strikes an object.

• Light bends around objects when it passes them.

A student tried to create an electrical circuit. He connects a wire to post A on the light fixture and the positive post of the battery as shown in the picture below. What other steps does the student need to complete to create an electrical circuit?

• Add a wire to post B on the light fixture and connect it to the positive post of the battery

• Add a wire to post A on the light fixture and connect it to the positive post of the battery

• Add a wire to post B on the light fixture and connect it to the negative post of the battery

• Add a wire to post A on the light fixture and connect it to the negative post of the battery

A class observed that when white light is passing through a prism at a certain angle, the light changes to a rainbow pattern as it exits the prism at a different angle. What claim best explains the behavior of the light passing through a prism?

• The light reflected from the prism created a rainbow.

• The light bounces off the prism in different colors.

• Colored light enters the prism and changes to white light.

• Light refracts as they pass through the glass prism.
