Waves Transfer Energy Flashcards
substance through which wave moves
Medium
A wave such as a sound wave seismic wave that transfers kinetic energy through matter
Mechanical waves
A type of wave in which the disturbance moves at right angles or perpendicular to the direction in which the wave travels
Transverse waves
A type of wave in which the disturbance moves in the same direction that the wave travels
Longitudinal waves
The highest point or peak of a wave
Crest
The lowest point or valley of a wave
Trough
The maximum distance that a distance that a disturbance cause a medium to move from its rest position;the distance between crest and trough of a wave and line through the center of a wave
Amplitude
The distance from one wave peak or crest to the next peak or crest. Wavelength can be measured as the distance from any part of the next wave.
Wavelength
The number of waves that pass a fixed point in a given amount of time, usually one second; the the number of cycles per unit time.
Frequency
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 the waves as they pass through an opening or around and he edge of an obstacle.
Diffraction
The meeting and combing of waves;the adding or subtracting of waves amplitudes that occurs as waves overlap.
Interference
A disturbance that transfers energy from one place to another without requiring matter to move the entire distance
