compressional wave | mechanical wave that douses particles to move back and forth along the direction the wave travels. |
diffraction | bending of waves around an object |
electromagnetic spectrum | complete range of electromagnetic wave frequencies and wavelengths. |
electromagnetic waves | waves that can travel through matter or empty space. |
frequency | number of wavelengths that pass a given point in one second |
infrared waves | electromagnetic waves with wavelengths between about one thousandth of a meter and 700 billionths of a matter. |
intensity | amount of energy a wave carries past a certain area each second |
law of reflection | states that the angle the incoming wave makes with the normal to the reflection surface. |
pitch | human perception of the frequency of sound. |
refraction | change in direction of wave when it changes speed as it travels from one material into another. |
reverberation | repeated echoes of sound waves. |
transverse waves | mechanical wave that causes particles in matter to move at right angles |
ultraviolet waves | electromagnetic wave with wave lengths between about 400 billionths and of mater |
wave | disturbance that moves trough matter and space and carries energy. |
wavelennght | space between one point on a wave and the nearest point moving with the same speed and direction. |
