Wave Basics
All waves move this
Energy
Waves pass through an object and come out the other side
transmission
Sound waves are collected by this part of the ear
outer ear
This is where EM waves start
sun and stars
______ absorbs all colors
Black
Waves do not move this
Matter
When wave energy gets soaked up and held by an object
absorption
Three small bones that amplify sound are in this part of the ear
middle ear
Particles in the EM Spectrum are called this
photons
_________ reflects all colors
white
These waves move up and down or side to side
Transverse
When waves are bounced back off of an object
reflection
Vibrations are changed to messages to be sent to the brain in this part
inner ear
EM waves must have a medium: True or False
False
Light travels in _______________ lines
straight
These waves move backward and forward
Longitudinal
When waves are bent
refraction
Sound waves are this type of wave
longitudinal
These two forces combine to make the EM spectrum waves
electricity and magnetism
An object must reflect or produce light to be seen: True or False
True
List the four parts of a wave
crest, trough, wavelength and amplitude
When wave energy changes direction
diffraction
Loudness of sound is measured in this unit
decibels
All of the waves in the EM spectrum can be seen or felt: True or False
False
This mnemonic device helps us remember the order of colors in light
