Science
Term | Definition |
---|---|
compressional wave | mechanical wave that causes articles in matter to move back and forth along the direction the wave travel |
diffraction | bending of waves around an object |
electromagnetic spectrum | complete range of electromagnetic wave frequencies and wave length |
frequency | number of wave length that pass a given point in one second, measured in hertz |
infrared waves | electromagnetic waves with wave lengths between about one thousandth of a meter and 700 billionth of a meter |
law of reflection | states that the angle the incoming wave makes with the normal to the reflecting surface equals the angle the reflected wave makes with surface |
pitch | human perception of the frequency of sound |
refraction | change in direction of a wave when it changes speed as it travels from one material into another |
reverberation | repeated echoes of sound waves |
transverse wave | mechanical wave that causes particles in matter to move at right angles to the direction the wave travels |
ultraviolet waves | electromagnetic waves with wave-length between about 400 billionths and 10 billionths of a meter |
wave | disturbance that moves through matter and space and carries energy |
wave length | distance between one point on a wave and the nearest point moving with the same speed and direction. |
intensity | amount of energy a wave carries past a certain area each second |
electromagnetic waves | waves that can traveled through matter or empty space, includes radio wave,infrared waves,visible light waves,ultraviolet waves,X rays,and gamma rays |
