The distance between successive crests, troughs, or identical parts of a wave.
What is wavelength
100
Combination of waves so that two or more waves overlap to produce a resulting wave of increased amplitude.
What is constructive interference
100
The return of light waves from a surface.
What is reflection
100
A series of alternate reinforcements and cancellations produced by the interference of two waves of slightly different frequencies. Heard as a throbbing effect in sound waves.
What are beats
100
The highness or lowness of a tone related to a wave's frequency.
What is pitch
200
The cone shaped disturbance created by an object moving at supersonic speed.
What is a shock wave
200
Term applied to two or more waves who's crest and troughs arrive at a place at the same time so that their effects reinforce each other.
What is "in phase" interference
200
The angle made by an incoming ray of light.
What is angle of incidence
200
For a vibrating body or medium, the number of vibrations per unit time.
What is frequency
200
The response of a body when a forcing frequency matches its natural frequency.
What is resonance
300
The SI unit of frequency.
What is Hertz
300
When the two waves have the same amplitude and their phases are spaced equally in angle.
Example: Noise canceling headphones
What is a canceled/ out of phase wave
300
The bending of an oblique wave of light when it passes from one transparent medium to another
What is refration
300
Describes a sound that has a frequency too high to be heard by the normal human ear.
What is ultrasonic
300
Describes the sound that has a frequency too low to be heard by the normal human ear.
What is infrasonic
400
A wave in which the medium vibrates in a direction parallel to the direction in which the wave travels.
What is a longitudinal wave
400
The pattern formed by super position of different sets of waves that produces reinforcement in some places and cancelation in others.
What is an interference pattern
400
This color has the longest wavelength.
What is red
400
Persistence of sound, as in an echo, due to multiple reflections
What is reverberation
400
Rarefied region of the medium through which a longitudinal wave travels.
What is rarefaction
500
A wave in which the medium vibrates in a direction perpendicular to the direction in which the wave travels.
What is a transverse wave
500
A stationary wave pattern formed in a medium when two sets of identical waves pass through the medium in opposite directions.
What is a standing wave
500
Light takes the path that requires the least time when it goes from one place to another.
What is Fermat's Principle of Least Time
500
A frequency at which an elastic object naturally tends to vibrate if it is disturbed and the disturbing forces are removed
What is natural frequency
500
Condensed region of the medium through which a longitudinal wave travels.
