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.
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.
The arrows in the diagrams below represent. Which diagram best shows how a glass mirror would reflect light?
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.
What happens when light hits an object that it cannot pass through?
The light is refracted or absorbed.
the light is reflected or absorbed.
The light is reflected or refracted.
The light is refracted or curved.
Students classify objects by the properties or reflection and refraction. Which is a list of objects that best reflect light?
Prism, water, camera
Water, Cardboard, clear container
Foil, shiny pan, mirror
Mirror, wood, water
Light travels into a camera lens to form a small, upside down image on the inside of the camera. Which of the following best describes why the lens flips and decreases the size of the image?
Light is refracted by the lens.
Light is absorbed by the lens.
Light is reflected by the lens.
Light is transmitted by the lens.
Sometimes it is possible to see light rays. An examples is when sunlight break s through the clouds. Sunlight breaking through the clouds demonstrates how light rays travel in --
curved rays
straight lines
zigzag rays
circular waves
Energy can change forms?
TRUE
FALSE
THERMAL energy
heat energy
cool energy
molten energy
loud energy
This shows energy changing from
_______ to _____ forms
Electrical to Sound
Thermal to Electrical
Electrical to Thermal
Thermal to Light
Electricity that flows in a closed path is called a
path
current
circuit
A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?
Light bulb 1 and light bulb 2 will both be on
Light bulb 1 will be off, but light bulb 2 will be on
Light bulb 1 and light bulb 2 will both be off
Light bulb 1 will be on, but light bulb 2 will be off
The diagram shows a series circuit with three lit bulbs. How many of the bulbs will remain lit if the wire is cut a the point shown by the arrow?
0
1
2
3
Will the light bulbs light up in this image?
Yes, both of them will
Yes, but only the one on the right
No, neither of them will
Yes, but only the one on the left
What is missing from this circuit? Why would the light bulbs be off?
The battery, there is no power for the circuit to work.
The switch is open, so the circuit is broken.
The third light bulb, that is needed to complete the circuit.
The wires are not connected properly.
What forms of energy does the sun provide?
chemical and thermal
light and thermal
sound and light
chemical and light
What types of energy come from a lightbulb when it is turned on?
chemical, light, heat
mechanical, light, heat
electrical, light, heat
electrical, sound, heat
Which property of light are the students observing in this situation?
F Light can be refracted and separated into different colors as it moves from air to a different medium.
G Light is refracted as it moves from one medium to another medium.
H Light travels in a straight line and can be reflected off the surface of water.
J Light is absorbed by water and reflected off glass.
A LEDs 1, 3, and 4 only
B LEDs 1, 2, 3, and 4
C LEDs 3 and 4 only
D LEDs 1, 3, 4, and 5
F travels in straight lines and reflects from the surface of the mirror
G refracts in the glass of the mirror and is spread out all over the room
H enters the mirror and changes direction when it is refracted by the back of the mirror
J travels through air and does not change its direction in air
A Open the switch and then connect the two wires that are attached to the wood block
B Switch the positions of the two wires that are connected to the battery and then open the switch
C Move the switch closer in the circuit to the battery
D Connect the two wires that are attached to the woodblock
What would cause refraction?
a mirror
a metallic pan
a hand lens
a pan balance
Sunlight can pass through our classroom windows because the windows are...
clean
opaque
translucent
transparent
Which of the following would probably reflect the most light?
Coffee cup
Notebook paper
Polished spoon
Wooden block
Which is NOT true about light?
It is refracted when it passes from air through water.
It is reflected when it bounces off the surface of water.
Light travels in a straight line through empty space.
Light is absorbed when it strikes a mirror.
The picture below demonstrates what happens to light when it passes through water in a glass. This is an example of:
light scattering
reflection
light absorption
refraction
In which circuit below is Bulb A on, but Bulb B is off?
A
B
C
D
What is occurring to the light when it comes in contact with the water?The light is scattering.
The light is scattering.
The light is reflected.
The water is absorbing the light.
The light passes through the water with no effect.
