Studying waves

Wave A disturbance that moves through matter or space, carries energy from one place to another.
Transverse Wave Causes particles in matter to move back and forth at right angles to the direction in which the wave travels, high points in the wave are called crests and low points are called troughs.
Compressional Wave Causes particles in matter to move back and forth along the same direction in which the wave travels.
Wavelength The distance between one point on a wave and the nearest point moving with the same speed and direction.
Frequency The number of wavelengths that pass by a point each second.
Law of reflection The angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal.
Refraction Is the change in direction of a wave when it changes speed as it travels from one material to another.
Diffraction Waves can change direction, which is the bending of waves around an object.
Opaque Allowing no light to pass through.
Translucent Allowing some light to pass through.
Transparent Allowing all light to pass through.
Reflect Hits a surface and then bounces back.
Absorb Take in or soak up.
Transmit When light hits an object, the light reflects.
Loudness The sound level, or how well a sound can be heard.
Pitch How high or low a sound is, determined by the frequency of the vibration.
Echo Location The location of objects by reflected sound, in particular that used by animals such as dolphins and bats.
Echo A reflection of sound.
Doppler Effect The change in frequency of a wave as its source moves in relation to an observer.
