The use of a sound wave created by an external source and directed along the positive column of a nitrogen discharge in order to make the discharge pass to the contracted state is studied experimentally. A phenomenon involving a jump in the sound wave amplitude, caused by the discharge contract...
<p>To answer the question about the wavelength, frequency, time period, and amplitude of a sound wave, we can break down each term step by step:</p><p><strong>Step 1: Define Wavelength</strong> - <strong>Wavelength (λ)</strong> is defined as the distanc
A sound wave with a higher frequency is perceived as having a higher pitch. A high frequency happens when a wave is traveling faster with a short wavelength. How is the amplitude of sound measured? The amplitude of a sound is measured using the SI unit: decibels (dB). The decibel number...
