Intensity in Physics | Definition & Formula from Chapter 5 / Lesson 10 48K This lesson explains what wave intensity in physics is, and it explains the intensity of light formula with examples. This lesson also describes how to calculate intensity of...
Loudness is a subjective perception that describes how strong or intense a sound appears to a listener, typically measured in decibels (dB). It depends on the amplitude of sound waves; higher amplitudes produce louder sounds. Pitch, on the other hand, is determined by the frequency of sound ...
Frequency response describes how a microphone captures different frequencies of sound. It indicates the microphone's ability to reproduce sounds across the audible spectrum and is usually represented graphically as a frequency response curve. A flat frequency response means the microphone captures all freq...
Thesample ratedescribes the number of snapshots taken of the original soundwave. The higher the sample rate, the closer the reproduction resembles the original. A CD’s sample rate of 44.1 kHz is standard for recorded music, and means that 44,100 samples are taken per second. ...
So, too, is F = ma, which describes forces acting on an object with respect to its mass and acceleration. Newton was a mathematician and a physicist, and those who have had advanced math may recognize F = ma as the quintessential example of the Chain Rule, central to Newton's system ...
Audible sound is produced by using electricity and is transmitted as eitheranalog or digitalsignals: This form of audio uses alternating current (AC) voltage to create a signal that coincides with the frequencies and amplitudes of the original soundwaves. An analog signal can be transmitted between...
Wag describes a quick, repetitive, side-to-side motion, often referring to an excited dog’s tail or as a gesture like shaking a finger. On the other hand, wave involves a smoother, rhythmic motion like the rolling of water or hand gestures used for greeting. 5 Wagging typically indicates...
Waveformdescribes the shape or form of a wave signal.Waveis typically used to describe an acoustic signal or cyclical electromagnetic signal because each is similar to waves in a body of water. Four basic types of waveforms exist: Sine wave.The voltage increases and decreases in a steady curve...
