Question | Answer |
frequency | Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial . |
trough | Trough may refer to: Trough (economics), the lowest turning point of a business cycle; Trough (food) or manger, a container for animal feed; Watering trough, ... |
compression | com·pres·sion (k m-pr sh n). n. 1. a. The act or process of compressing. b. The state of being compressed. 2. a. The process by which the working substance |
wavelength | In physics, the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats. It is usually determined |
wave | physics a wave is a disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy. Wave motion transfers energy |
transverse wave | transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. |
longitudinal wave | Longitudinal waves, also known as "l-waves", are waves whose direction of oscillation is the same as their direction of travel |
amplitude | The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period). There are various definitions of amplitude. |
crest | A crest is a component of an heraldic display, so called because it stands on top of a helmet, as the crest of a jay stands on the bird's head. The earliest heraldic. |
rarefaction | Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves |
energy | n physics, energy is a conserved extensive property of a physical system, which cannot be observed directly but can be calculated from its state |
