Question | Answer |
---|---|
wave | a periodic disturbance in a solid, liquid, or gas as energy is transmismitted through a medium |
medium | a physical environment in which phenomena occur |
transverse waves | a wave in which the particuls of the medium move perpendicuraly to the direction the wave is traveling |
longitudial wave | a wave in which the particles of the medium vibrate parallel to the direction of wave motion |
amplitude | the maximum distance that the particles of a wave's medium vibrate from their rest position |
wavelength | the distance from any point on a wave to an identical point on the next wave |
frequency | the number of waves produced in a given amount of time |
wave speed | the speed at which a wave travels through a medium |
reflection | the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through |
refraction | the bending of a wave as the wave passes between two substances in which the speed of the wave differs |
diffraction | a change in the direction of a wave when the wave finds an obsticle or an edge, such as an opening |
interference | the combonation of two or more waves that results in a single wave |
standing wave | a pattern of vibration tat simulates a wave that is stanging still |
resonance | a phenomenon that occurs when two objects naturally vibrate at the same frequency; the sound produced by one object causes the other object to vibrate |
