Physics ch 6,9
|A traveling disturbance consisting of coordinated vibrations that transmit energy with no net movement of matter.
|A wave in which the oscillations are perpendicular to the direction the wave travels.
|What are the examples of transverse waves?
|Waves on a rope, electromagnetic waves, some seismic waves.
|A wave in which the oscillations are along the direction the wave travels.
|What are some examples of longitudinal waves?
|Sound in the air, some seismic waves.
|The maximum displacement of points on a wave, measured from the equilibrium position.
|The distance between two successive "like" points on a wave, for example, the distance between two adjacent peaks or two adjacent valleys.
|The number of cycles of a wave passing a point per unit time. the number of oscillations per second in the wave.
|Light passing through material such as polaroid filters.
|Light bouncing of a surface.
|Light traveling through a material.
|When light strikes the atoms.
|The apparent change in the frequency of wave fronts emitted by a moving source, example is a train traveling along a track blowing a whistle.
|Is the process of using the waves reflected from an object to determine its location.
|What are some examples of echolocation?
|Radar and sonar.
|Arises when two continuous waves, usually with the same amplitude and frequency, arrive at the same place.
|Is a sound with a sinusoidal waveform.
|Is a complex sound wave. The waveform of a complex tone repeats itself but is not sinusoidal.
|Is determined mainly by the amplitude of the sound wave. The greater the amplitude of the sound wave that reaches your eardrums, the greater the perceived loudness of the sound.
|A sound is the perception of highness or lowness. The sound of a soprano voice has a high pitch and that of a bass voice has a low pitch. The pitch of a sound depends primarily on the frequency of the sound wave.
