Mr. Tubb Project 2012
Transcript of Mr. Tubb Project 2012
10/19/12 Mr. Tubb's Class Project A-1 transverse wave- trough- The part of a wave with the least magnitude; the lowest part of a wave. Compare crest. sound- intensity- decibel-A decibel is the
degree of loudness crest- vibration- hertz- the basic unit of frequency asd asdsad longitudinal wave- mechanical wave- wave- frequency- vacuum-A vacuum is a space devoid of air or matter medium- amplitude- pitch- wavelength- diffraction- Diffraction refers to a process by which light waves break up into dark and light bands or into the colors of the spectrum. reflection- The change in direction of a wave, such as a light or sound wave, away from a boundary the wave encounters. A wave vibrating in the direction of propagation. waves that travel in a material medium, such as water waves
A wave vibrating at right angles to the direction of its propagation swing - flutter Frequency is how often something happens A substance that makes possible the transfer of energy from one location to another, especially through waves Sound is vibration in air and water that stimulate the nerves inside the ears to create the sensation of hearing. the amount of force or energy of heat, light, sound, electric current, etc. per unit area, volume, charge, etc. amplitude refers to the length and width of waves, such as sound waves, as they move or vibrate. The pitch of a sound is also known as its frequency. When the frequency is high, the wavelength of the sound is shorter The part of a wave with greatest magnitude; the highest part of a wave the distance
between the crest
of a wave refraction- bending of a light or heat wave movement back
