Waves And Energy 1.1 Flashcards
Any substance that has a wave move through.
Medium
A wave, such as a sound wave or 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 highest point or peak of a wave
Crest
The lowest point or valley of a wave
Trough
The maximum distance that a disturbance causes a medium to move from its rest position; the distance between a crest or trough of a wave and line through the center of a wave
Amplitude
The distance from one wave leak or crest to the next peak or crest. Wavelength can be measures as the distance from any part of one wave to the identical part of the next wave.
Wave length
The number of waves passing a fixed point in a certain amount of time
Frequency
The bouncing back of a wave after it strikes barrier
Reflection
The bending of a wave as it crosses the boundary between two mediums at an angle other than 90°
Refraction
The spreading out of waves as they pass through an opening of around the edges of an obstacle
Diffraction
The meeting and combing of waves; the adding of subtracting of wave 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.
