Wave Anatomy
The name of the highest point on a wave
A Crest
This kind of wave is created when an object vibrates
Sound Wave
We hear the frequency of a sound wave as this.
Pitch
How often a wave repeats itself
Frequency
The speed of a wave can be calculated by multiplying these two things together
Frequency and Wavelength
The height of a wave at a crest or a trough
Amplitude
This type of wave does not require a medium, and can even travel through empty space
Electromagnetic wave
We hear the amplitude of a soundwave as this
Volume (Loudness)
The unit used for frequency
Hertz, Hz
What fraction of a standing wave can be measured from a node to its nearest antinode?
1/4
The distance between 2 identical points in a wave (crest-crest, trough to trough)
Wavelength
This type of wave requires a medium to travel through
Mechanical Wave
The lowest frequency sound that can come from an object
The fundamental Frequency
The material needed for a mechanical wave to travel through.
A medium
(or a solid, liquid or a gas)
The wave speed of a wave with a frequency of 440 Hz and a wavelength of 0.7 m
308 m/s
A location on a standing wave that does not move
Node
In this type of wave, the particles move up and down (like a ripple in a pond)
Transverse
A frequency that is a multiple of the fundamental frequency of an object
A Harmonic
Name 3 examples of sources of Electromagnetic Waves
Examples:
Gamma Rays Infrared
X Rays Microwaves
Ultraviolet Radiowaves
Visible Light
The wavelength of a wave with a frequency of 600 Hz traveling at a speed of 250 m/s.
0.417 m
A location on a standing wave that moves the most
Antinode
This type of wave moves back and forth in the same direction the wave travels
Longitudinal Wave
The tendency of an object to vibrate with increasing amplitudes when reacting to certain frequencies
Resonance
How quickly energy in a wave travels from one location to another
Wave Speed
The frequency of a sound wave with a wavelength of 0.68m traveling at 340 m/s
500 Hz
