longitudinal wave/ compressional wave
Waves like sound that move energy in the same direction as the wave. (moves horizontally)
transverse wave
Waves like light that move energy at right angles to the direction the wave moves. (moves up and down or side to side)
mechanical wave
Waves that must have a medium to travel
crest
top part of the wave
trough
bottom part of the wave
amplitude
distance a wave moves from the resting position
frequency
number of full waves that pass in specific amount of time
wavelength
distance between two similar parts of a wave
Transmission
waves are able to pass through a medium
absorbtion
wave energy is not transferred through a medium
reflection
bouncing back of a wave when it meets a surface or a boundary
refraction
bending of waves due to a change in speed as they enter a new medium
compression
the more dense portion of the wave
rarefraction
the least dense portion of the wave
medium
Any solid, liquid or gas that allows a wave to travel
transparent
images can be see and are not distorted
translucent
allows light to pass through but images are foggy or haze and unclear
opaque
does not allow light to pass through
black
the absorption of all light
white
the reflection of all light
the color we see
the wavelength of light that is reflected to our eye
Cornea
transparent tissue that transmits and refracts light to the pupil. The outside coating that protects against dust, eyelashes, etc.
Iris
colored muscle that gets bigger and smaller to let in different amounts of light.
pupil
the dark colored hole that lets light into the inner parts of the eye.
retina
inside back wall of the eye. It sends signals to the brain through nerves so we can see an image.
optic nerve
Relays messages from the retina to the brain
Electromagnetic spectrum
The range of transverse waves that travel to us from space ranging from radio waves to high energy gamma rays
