Physics ch 6,9

Waves A traveling disturbance consisting of coordinated vibrations that transmit energy with no net movement of matter.
Transverse wave 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.
Longitudinal wave 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.
Amplitude The maximum displacement of points on a wave, measured from the equilibrium position.
Wavelength The distance between two successive "like" points on a wave, for example, the distance between two adjacent peaks or two adjacent valleys.
Frequency The number of cycles of a wave passing a point per unit time. the number of oscillations per second in the wave.
Transmission Light passing through material such as polaroid filters.
Reflection Light bouncing of a surface.
Refraction Light traveling through a material.
Scattering When light strikes the atoms.
Doppler effect 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.
Echolocation Is the process of using the waves reflected from an object to determine its location.
What are some examples of echolocation? Radar and sonar.
Interference Arises when two continuous waves, usually with the same amplitude and frequency, arrive at the same place.
Pure tone Is a sound with a sinusoidal waveform.
Complex tone Is a complex sound wave. The waveform of a complex tone repeats itself but is not sinusoidal.
Loudness 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.
Pitch 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.
