|
Energy can be transferred from a source to a reciever without the transfer of matter between two points
|
Wave motion
|
|
|
High points of a sine wave
|
Crests
|
|
|
The low points of a sine wave
|
Troughs
|
|
|
The distance from the top of one crest to the top of the next one.
|
Wavelegnth
|
|
|
Related to the frequency and wavelegnth of the waves.
|
Wave speed
wvlgth x freq |
|
|
How frequently a vibration occurs
|
frequency
|
|
|
The time for one complete vibration
|
Period
|
|
|
The distance from the midpoint to the crest or trough of the wave
|
Amplitude
|
|
|
Right-angled, sideways motion. The motion is transverse to the direction the wave travels.
|
Transverse wave
|
|
|
Parts that make up a medium move to and fro in the same direction in which the wave travels. Motion along the direction of the wave, not at right angles
|
Longitudinal wave
|
|
|
When one the crest of one wave overlaps the crest of another, their individual effects add together to produce a wave of increased amplitude
|
Consturctive interference
|
|
|
When the crest of one wave overlaps the trough of another, their individual effects are reduced.
|
Destructive interference
|
|
|
A wave in which parts of the wave, called nodes, are stationary
|
Standing wave
|
|
|
Give 3 examples of everyday longitudinal and trasverse waves
|
T-
|
|
|
An echo
|
Reflection
|
|
|
Must be present for sound to travel through
|
medium
|
|
|
A pulse of compressed air
|
Compression
|
|
|
Travels at 340 m/s
|
Speed of sound in air
|
|
|
The _____ of a sound relates to its frequency
|
Pitch
|
|
|
High frequency produces a _____ note, and low frequency produces a ____ note
|
High/low
|
|
|
Depends on the amplitude of pressure variations within the sound wave.
|
Intensity
|
|
|
A physiological sensation
|
Loudness
|
|
|
Phenomenon that occurs when the frequency of forced vibrations on an object matches the object's natural frequency,producing a dramatic increase in amplitude
|
Resonance
|
|
|
Chnage in frequency of a wave of sound or light due to the motion of the source or the reciever.
|
Doppler effect
|
