when a wave bends as it moves from one medium to another, this is called __________
refraction
As the wavelength increases, the energy ___________
decreases
Which type of wave is this?
longitudinal
Which property of a wave do we use to represent the pitch?
frequency
A wave carries ___________
energy
What is the relationship between frequency and wavelengh?
they are inversely related
define constructive interference
when two waves overlap and create a larger amplitude wave
define wavelength
distance between 2 crests or troughs
sound travels slowest in ______
gas or air
the speed of light is (miles per hour or meters per second
~670,000,000 mph or 300,000,000m/s
Which type of wave is this?
transverse
Which wave moves parallel with the medium vibrations.
longitudinal
Define crest
the top curve of a transverse wave
define compression
in a longitudinal wave where the particles are bunched together
define rarefaction
in a longitudinal wave, where the particles are spread apart
Which wave moves perpendicular to to the medium (if there is one)
tranSverSe
How are sound and light waves different with respect to a medium?
Sound requires a medium, light does not.
Waves are caused by ______
vibrations
Define trough
the bottom curve of the wave
The two properties that increase energy if you increase them are:
frequency and amplitude
When instrumentalists tune their instruments they are listening for __________ ______
interference patterns
when an object vibrates at a certain frequency, we call that its ____________
resonance
define destructive interference
when waves overlap and cancel each other out
