waves
Question | Answer |
---|---|
compressional waves | mechanical wave that causes particles in matter to move back in forth along the direction the wave travels |
diffraction | waves can change direction which is the bending of waves around an object. |
electromagnetic spectrum | complete range of electromagnetic wave frequencies and wavelength |
electromagnetic waves | waves that can travel through matter or empty space includes radio waves in fared waves visible light waves ultraviolet waves x rays and gamma rays |
frequency | The frequency of a wave is the number of wave lengths that pass by a point each second. |
infrared waves | electromagnetic waves with wavelength between about one thousandth of a meter and 700 billionths of a meter |
intensity | amount of energy a wave carries past a certain area each second |
law of reflection | According to law of fraction the angles that the incoming wave make the normal equals the angle that the outgoing wave makes with the normal. |
pitch | as it relates to sound |
refraction | Refraction is the change in direction of a wave when it changes speed as it travels from one material to another. |
reverberation | repeats echoes of sound sound waves |
transverse wave | A transverse wave causes particles in matter to move back and forth at right angles to the direction in which the wave travels. |
ultraviolet wave | electromagnetic waves with wavelength between about 400 billionth and 10 billionths of a meter |
wave | A wave is a disturbance that moves through matter or space. |
wavelength | The distance between one point on a wave and the nearest point moving with the same speed and direction is the wavelength. |
