Waves and Sound
What do we call the substance that a wave needs to travel through?
A medium
This triangular piece of glass was used by Newton to separate white light into all of the colors of the rainbow.
Stainless steel spoons, aluminum pipes and tin cans are all examples of good
Conductors
Electric current is due to the motion of what?
This is the value which describes that height of a wave.
What type of wave pushed matter back and forth as it travels?
Compressional Wave
This is the portion of the electromagnetic spectrum that includes all of the light that can be seen by the human eye.
The visible spectrum
Describe the direction that heat will flow between a hot cup of tea and the surrounding air.
Heat flows from the tea (high hear energy) to the air (low heat energy).
This type of circuit has only one pathway for electric current to travel.
Series circuit
This is the type if heat transfer which occurs through direct contact.
Conduction
This is the area of a wave where particles are pushed close together.
Compression
Radio, microwaves, infrared, visible light and x rays are all examples of what type of wave?
Electromagnetic wave
This type of heat transfer can be felt coming from a stove top burner without touching it.
Radiation
This is included in a circuit to reduce the amount of current that is allowed to pass through.
A resistor
If a red piece of paper was brought into a room lit by only green light, what color would that piece of paper appear to be?
Black
What is the measure of how many wave crests pass a given point in a unit of time?
Frequency
Mixing all visible colors will product this "color".
White
Pasta cooking in a large pot of water appears to rise in the middle and sink at the edges. This demonstrates which type of heat transfer?
Convection
A student attempts to make an electromagnet by wrapping a wire around an iron nail. What else is needed to make the electromagnet work?
An electric current OR a battery
This is the change in the direction of a wave due to a change in the medium
Refraction
This is the name of the effect that causes a change in frequency of a wave if either its sources or listener is moving?
The Doppler Effect
An object which is yellow reflects what color light?
Yellow
A 3.0 kilogram sample of water will retain heat for a longer length of time than a 3.0 kilogram sample of aluminum. This demonstrates what property of matter?
Specific heat
This is the pathway that allows extra electric charges to move out of a charged object.
Ground OR electrical ground OR grounding
If three light bulbs are connected to a circuit, which type of circuit would allow one bulb to burn out but still keep the other bulbs lit.
Parallel circuit.
