Sagot :
If the frequency of the sound wave is 2π/3, then the time period of the sound wave will be 0.447 seconds. Then the amplitude is 14.
What is wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
A sound wave is modeled with the equation y = 14 cos (2π/3) θ.
The frequency of the sound wave will be
[tex]f = \dfrac{2\pi}{3}[/tex]
Then the time period will be
[tex]T = \dfrac{1}{f}\\\\T = \dfrac{1}{2\pi /3}\\\\T = \dfrac{3}{2\pi}\\\\T = 0.477 \ \rm seconds[/tex]
Then the amplitude of the sound wave will be
A = 14
