What is a wave?
|
A method of transferring energy from one place to another w/o the transfer of matter
|
|
What is energy?
|
The ABILITY to do work
|
|
What is a transverse wave?
|
a WAVE in which the medium vibrates PERPENDICULAR to the direction the wave energy travels
|
|
What is a medium?
|
Material or substance that the wave energy travels
|
|
What is reflection
|
Bouncing of a wave off of the boundary between 2 different media (plural medium)
|
|
What is dissipation?
|
Decrease in energy of a wave, as it travels further and further from the source.
|
|
What is Refraction?
|
Bending of a wave as it passes from one medium to another b/c of a change in speed
|
|
What is a Boundary
|
point of contact between 2 different media
|
|
What is a wavelength?
|
distance from one point on a wave to the same point on the next consecutive wave
|
|
What is a crest?
|
Upper displacement of the particles of the medium away from equilibrium
|
|
What is a trough?
|
Downward displacement of the particles of the medium away from equilibrium
|
|
What is the equation for frequency?
|
# of wavelength ÷ unit of time
|
|
What is amplitude?
|
maximum displacement of the particles of the medium away from equilibrium
|
|
What is color?
|
The human interpretation of the frequency of a light wave
|
|
(Type of light)
|
All of the frequencies of the white light are absprbed except ________ frequency which is reflected.
|
|
Brightness/dimness
|
human interpretation of the amplitude of a light wave
|
|
What is a longtidunal wave?
|
wave in which particles of the medium vibrate PARALLEL to the direction which the wave energy travels
|
|
What is a compression?
|
The are of longitudinal wave in which the particles of the medium are more dense then at Xo
|
|
What is a rarefaction?
|
The are of a longitudinal wave in which the particles are less dense then at Xo
|
|
Pitch-
|
human interpretation of a sound wave
|
|
Loudness/Quietness
|
human interpretation of a sound wave
|
|
interference--
|
when 2 or more similar waves pass through the same medium at the same time, the resulting wave form is the additive sum of each of the waves
