What is created by a disturbance that travels through a medium?
What is a wave?
100
This is the highest part of a transverse wave, not toothpaste.
What is a crest?
100
The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium.
What is amplitude?
100
The bouncing back of an object or a wave when it hits a surface through which it cannot pass.
What is reflection?
100
The material (not too big, and not too small) through which a wave travels.
What is a medium?
200
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
What is a transverse wave?
200
The lowest part of a transverse wave.
What is a trough?
200
This wave travels the fastest
What is longitudinal
200
The bending of waves as they enter a new medium at an angle.
What is refraction?
200
These waves or types of waves can travel through space
What are transverse waves or light waves or electromagnetic waves
300
A wave that moves the medium in a direction parallel to the direction in which the wave travels.
What is a longitudinal wave?
300
These are points where two waves meet when they cross each other. These points are evenly spaced out throughout the wave.
Node
300
The number of complete waves that pass a given point in a certain amount of time.
What is frequency?
300
The bending of waves as they move around a barrier or pass through an opening.
What is diffraction?
300
The rule that the angle of reflection equals the angle of incidence.
What is the law of reflection?
400
A wave that appears to stand in one place, even though it is really two waves interfering as they pass through each other.
What is a standing wave?
400
The distance measured from the top of one crest to the top of the next crest
What is a wavelength ?
400
Unit of measurement for frequency.
What is a hertz (Hz)?
400
What is the difference between constructive and destructive interference?
Constructive makes the amplitude larger and does not destroy a wave - these waves meet, create a larger amplitude, and then continue on their way
Destructive makes the amplitude smaller and does destroy the smaller wave (the larger wave overtakes the smaller wave but the larger wave's amplitude gets smaller)
400
Name the three ways light acts, define each term, and give an example of each
Transparent, can totally see through, a clear window
Translucent, can partially see through, stained glass window
Opaque, cannot see through and casts a shadow, a wall
500
An earthquake wave is also know as a
Seismic wave
500
A point of maximum amplitude on a standing wave.
What is an antinode?
500
The frequency of 300 waves that pass a point in 60 seconds?
What is 5 Hz?
500
The increase in the amplitude of a vibration that occurs when external vibrations match an object’s natural frequency.
What is resonance?
500
What is red shift? Give two important facts about this.
Evidence that the universe is expanding
Objects in space are moving away from us so it produces a reddish color because of the longer wavelength
When they move away, the frequency is decreasing
When light is moving towards something, it produces a blueish color because the wavelength is shorter and the frequency is increasing
