Energy
Which type of wave moves matter forward and backward in the medium in the same direction as the wave?
Longitudinal Wave.
Draw and Label a high frequency wave and a low frequency wave
^ v ^ v ^ v
^v^V^V
The rhythmic disturbance that carries energy and NOT matter
a Wave!
Materials that block light from passing through
Opaque
A compressional wave is also known as a _________
longitudinal wave
Materials that allow light to pass through clearly.
Transparent
When a surface throws back a wave without absorbing it
Reflection
Which type of wave needs a medium to transfer energy?
mechanical
The region of a longitudinal wave where the particles are close together
Compression
When atoms in matter absorb light
Absorption
The measure of energy of the height of a wave
amplitude
The region of a longitudinal wave where the particles are farther apart (less dense).
Rarefaction
The type of wave sound is
The type of wave light is
Electromagnetic
When light changes direction between one medium and another.
Refraction
The type of wave that has areas of compression and rarefaction.
Compressional/longitudinal
Materials that allow light to pass through but diffuse it, obscuring distinct details
Translucent
