Question | Answer |
---|---|
diffraction | bending of waves around an object |
electromagnetic wave | waves that can travel through matter or empty space, includes radio waves, infrared waves, visible light waves, ultraviolet waves, X rays, and gamma rays |
electromagnetic spectrum | complete range of electromagnetic wave frequencies and wavelengths |
compressional wave | mechanical wave that causes particles in matter to move back and forth along the direction the wave travels |
transverse wave | mechanical wave that causes particles in matter to move at right angles to the direction the wave travels |
pitch | human perception of frequency sound |
intensity | amount of energy a wave carries past a certain area each second |
infrared waves | electromagnetic waves with wavelengths between about one thousandth of a meter and 700 billionths of a meter |
reverberation | repeated echoes of sound waves |
wavelength | distance between one point on a wave and the nearest point moving with the same speed and direction |
wave | disturbance that moves through matterand space and carries energy |
frequency | |
refraction | |
ultraviolet waves | |
law of reflection | |
