QuestionAnswer
a periodic disturbance in a solid, liquid, or gas wave
a physical environment in which phenomena occur medium
a wave in which the particles of a medium move perpendicularly to the direction the wave is traveling transverse wave
a wave in which the particles of the medium vibrate parallel to the direciton of the wave motion logitudinal wave
the maximum distance that the particles of a wave's medium vibrate from their rest position amplitude
the distance from any point on a wave to an identical point on the next wave wavelength
the number of wves produced in a given amount of time frequency
the bouncing back of a ray of light, sound, or heat when the ray hits the surface and doesnt go through reflection
the bending of a wave as the wave passes between two substances in which the wave differs refraction
a change in the direction of a wave when the wave finds an obstacle or an edge diffraction
