Sound I
What kind of energy is sound?
Mechanical energy
What kind of energy is light?
Radiant energy
Amplitude determines the __________ of sound.
When waves are not absorbed, but bounced off of a surface
reflection
The height of a wave from rest position.
amplitude
What kind of wave does sound travel through?
longitudinal wave
What kind of wave does sound travel through?
Transverse wave
Frequency determines the ___________ of sound
pitch
When waves are taken into an object
absorption
The highest point on a transverse wave
crest
What do sound waves require to travel? Name the three.
A medium; solid liquid and gas
True or false: light can travel through both a medium and through space (a vacuum)
True
When amplitude increases, what happens to volume?
volume increases, gets louder
When waves bend and change; like putting a pencil in water and it looks like it is broken.
refraction
The lowest point on a transverse wave
trough
True or false: Sound can travel through space (a vacuum).
False
Is light faster or slower than sound?
faster
When frequency increases, what happens to pitch?
The bending of waves as they pass an edge or an obstacle, new waves are created
diffraction
The area on a longitudinal wave where the particles are close together
compression
Is sound faster or slower than light?
slower
Light is a part of which spectrum?
Electromagnetic spectrum
What happens to frequency when wavelength increases?
Frequency decreases
When waves completely pass through a medium
transmission
The area on a longitudinal wave where the particles are spread out
rarefaction
