Wave Phenomena
Wave Motion
Hearing
100
Distance between two peaks in a wave
Wavelength
100
Disturbance that moves energy from one place to another
Wave
100
The angle of incidence equals the angle of reflection
Law of reflection
100
Waves in which the displacement of the medium is in the same direction of the wave movement
Longitudinal Waves
100
Which animal has the highest frequency of hearing?
Bat
200
Time it takes for a wave to make one complete cycle
Wave Period
200
When something moves back and forth or up and down at a regular motion.
Oscillation
200
The bending and spreading out of waves as they pass corners or obstructions
Diffraction
200
Wave whose oscillations are perpendicular (right angled) to the direction of energy transfer
Transverse Waves
200
Which animals have the lowest frequency of hearing?
Dogs, Dolphins, and Fish
300
Distance between the rest position and the highest or lowest point of the waves motion
Amplitude
300
Number of waves that pass a fixed point in a given amount of time
Wave Frequency
300
Change of direction due to a wave speeding up or slowing down
Law of Refraction
300
They have characteristics of both transverse and longitudinal waves
Surface Waves
300
Caused by a build up of fluid behind the eardrum
Ear Infection
400
Time it takes a wave to make 1 cycle is measured in ________.
Seconds
400
We measure the number of waves that pass a fixed point in a given amount of time in this SI unit.
Hertz
400
An increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other
Doppler Effect
400
Example of a transverse wave
ripples on the surface of water.
vibrations in a guitar string..
electromagnetic waves – eg light waves, microwaves, radio waves.
seismic S-waves
400
These are put in your ear to help release fluid
tubes
500
The longer the wavelength the _______ the frequency.
Lower
500
The shorter the wave length the __________ the frequency.
Higher
500
The reason that you hear the bass drum first when a marching band is approaching you
Low frequency sounds produce longer waves that due to diffraction spread out around corners while high pitch instruments produce short waves that we can't hear.

How do we hear sound waves?
Sound waves are trapped in by the outer ear and travel down the ear cannel to the middle ear. It vibrates though the middle ear to the cochlear which changes it to electrically impulses that are sent to the brain.
