What wave is that?
Plucking a guitar string...is an example of?
a transverse wave
Definition of longitudinal waves
A wave where the medium moves back and forth in the same direction as the wave.
this thing curves inward, spreading out light waves. Also used on nearsighted people.
concave lenses
Definition of a wave
A disturbance that carries energy from place to place
reading in front of a lamp...is an example of?
a light wave
parts of longitudinal waves
compression and rarefraction
this thing have an outward curve that sends light waves curving inward into a focal point. People with farsightedness use it.
convex lenses
definition of refraction
bending of a wave as it passes through 1 medium to another.
Someone sun-tanning...is an example of?
an Electromagnetic wave (ultraviolet light)
Part of longitudinal waves that is spread apart.
rarefraction
if the wave has a shorter wavelength, is the frequency shorter or taller?
taller
definition of diffraction
the bending of a wave as it passes around an object or through an opening, spreading the wave out.
an earthquake...is an example of?
a longitudinal wave
definition of transverse waves
A wave where the medium moves a right angles in the direction of the wave.
sound characteristics
pitch and loudness
definition of constructive interference
when 2 or more waves combine to make a wave with a greater amplitude than the original waves.
2 people having a conversation...is an example of?
a sound wave
parts of transverse waves
crest and trough
if the frequency is high, what happens to the amplitude?
its also high
definition of destructive interference
where 2 waves combine to make a wave with a smaller amplitude, or 1 that cancels the other out.
