Waves
Term | Definition |
---|---|
Compressional Wave | Mechine made that causes particles in matter 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 wavelength |
Electromagnetic Wave | Waves that can travel through matter or empty space includes radio waves infrared wave X rays and gamma rays |
Frequency | Number of wavelengths that pass a given point in one second measured in hertz |
Infrared Waves | Electromagnetic waves with wavelengths between about one thousandth of meter and 700 billionths of a meter |
Intensity | Amount of energy a wave carries past a certain area each second |
Law of Reflection | States that the angel the incoming wave makes with the normal to the reflecting surface equals the angle the reflected wave makes with the surface |
Pitch | Humans 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 | a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane |
Ultraviolet Wave | light is electromagnetic radiation with a wavelength from 400 nm to 10 nm, shorter than that of visible light but longer than X-rays. |
Wave | a long body of water curling into an arched form and breaking on the shore. |
Wavelength | the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. |
