Term
absorption
Definition
the transfer of energy carried by light waves to particles of matter
Term
diffraction
Definition
the spreading out of waves as they pass through an opening or around an obstacle
Term
echo
Definition
a reflected sound wave
Term
frequency
Definition
the number of waves produced in a given amount of time
Term
interference
Definition
occurs when two or more waves overlap
Term
medium
Definition
a substance through which a wave can travel
Term
translucent
Definition
material that transmits some light but also scatters some light in different directions
Term
pigment
Definition
a material that gives a substance its color by absorbing some colors of light and reflectin others
Term
refraction
Definition
the bending of a wave as it passes at an angle from one medium to another
Term
scattering
Definition
the release of light energy by particles of matter that have absorbed energy
Term
noise
Definition
any undesired sound that includes a random mix of pitches
Term
transparent
Definition
material that allows light to pass through without refraction
Term
wave
Definition
any disturbance that transfers energy through matter or space
Term
amplitude
Definition
half the distance from crest to trough; height of a wave
Term
longitudinal wave
Definition
a wave in which the particles of the medium vibrate back and forth along the path that the wave travels
Term
electromagnetic spectrum
Definition
the entire range of electromagnetic waves
Term
electromagnetic wave
Definition
wave that can travel through space or matter and consists of changing electric and magnetic fields
Term
opaque
Definition
material that does not allow light to pass through
Term
pitch
Definition
how high or how low a sound is perceived to be
Term
radiation
Definition
transfer of heat without matter
Term
reflection
Definition
occurs when a wave bounces back at the same angle after striking a surface
Term
resonance
Definition
what occurs when an object vibrating at or near a resonant frequency of a sound object causes the second object to vibrate
Term
sonic boom
Definition
the explosive sound heard when a shock wave from an object travels faster than the speed of sound reaches a person's ears
Term
sound quality
Definition
the result of several pitches blending together through interference
Term
standing wave
Definition
a wave that forms a stationary pattern in whcih portions of the wave do not move and other portions move with a large amplitude
Term
transmission
Definition
passing of waves through a medium
Term
transverse wave
Definition
wave that transferes energy in a direction that is perpendicular to the medium
Term
wave speed
Definition
the speed at which a wave travels
Term
wavelength
Definition
the distance between two adjacent crests or troughs in a series of waves
