Waves
Term | Definition |
---|---|
Wave | A disturbance that moves through matter or space |
Transverse Wave | Causes particles in matter to move back and forth at right angles |
Compressional wave | Causes particles in matter to move back and forth along the same direction |
Wavelength | The distance between one point on a wave and 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 | The change in direction of wave when it changes speed as it travels from one material to another |
Diffraction | Bending of waves around an object |
Loudness | As the amplitude (energy) increases the sound gets louder |
Pitch | As the amplitude (energy) decreases the sound gets softer |
Echo Location | |
Echo | A reflected sound wave |
