Sound Waves Flashcards
A substance through which a wave moves
Medium
A wave such as a sound wave or a seismic wave that transfers kinetic energy through matter
Mechanical wave
A type of wave in which the disturbance moves at right angles or perpendicular to the direction in which the wave travels
Transverse wave
A type of wave in which the disturbance moves in the same direction that the wave travels
Longitudinal wave
The bouncing back of a wave after it strikes a barrier
Reflection
The bending of a wave as it crosses the boundary between two mediums at an angle other than 90 degrees
Refraction
The spreading out of waves as they pass through an opening or around the edges of an obstacle
Diffraction
The meeting and combining of waves
Interference
The highest point of a wave
Crest
The lowest point of a wave
Trough
The maximum distance that a disturbance causes a medium to move from its rest position
Amplitude
The distance from one wave peak or crest to the next peak or crest
Wavelength
The number of waves that pass a fixed point in a given amount of time
Frequency
A disturbance that transfers energy from one place to another without requiring matter to five the entire distance
