Types of waves
The three types of mechanical waves
Longitudinal, transverse and surface
The is the length of a wave
Wavelength
This is a wave bouncing off of a surface, the incoming wave comes in at the same angle as it bounces off of the surface with
Reflection
A mirror is used to see our image, it also _______________________ light waves
Relfects
This is wave speed
How fast a wave travels
THese waves vibrate parallel to the direction of the wave's motion
Longitudinal
This is the height of a wave
Amplitude
This is a wave entering a new medium, slowing down and changing its direction
Refraction
Eye glasses, telescopes, microscopes and glasses of water are used to _____________________ light waves
Refract
This is the speed of a wave traveling if its frequency is 4 Hz and its wavelength is 2.5 m.
10 m/s
These waves vibrate perpendicular to the direction the waves are traveling
transverse
This is the highest point of the wave
Crest
This is a wave bending around an obstacle or moving through a small opening and spreading out on the other side.
Diffraction
Instruments that make music rely on this in order to make their sounds louder
Standing waves or resonance
This is the period of a wave that has a frequency of 4 Hz.
What is 0.25 s
These waves vibrate the particles of the medium in a circular pattern
Surface
This is the lowest point of the wave
trough
This is two or more waves interacting in destructive or constructive way
Interference
A singer can break glass with their voice because of this
Standing waves or resonance
This is the result of a crest of one wave meeting the trough of another wave
Canceling or destructive interference
These are examples of each type of wave
Longitudinal- sound
Transverse- Light
Surface- Earthquake
This is the number of waves in one second
Frequency
This is two waves, an incoming and reflected wave interacting in one spot at the same time cause a wave that doesn't appear to move
Standing wave
Acoustic engineers design auditoriums to handle a variety of sound waves reflecting off of surfaces so there are no "dead zones". These engineers must understand ______________________ to accomplish this.
Interference
This is the result of a crest of one wave interacting with the crest of another wave
Constructive interference
