Question
Use the wave equation to find the speed of a wave given by$$y(x, t)=(2.00 \mathrm{mm})\left[\left(20 \mathrm{m}^{-1}\right) x-\left(4.0 \mathrm{s}^{-1}\right) t\right]^{0.5}$$
Step 1
Step 1: The given wave equation is in the form of $y(x, t)=A[f(kx-\omega t)]$, where $A$ is the amplitude, $k$ is the wave number, $\omega$ is the angular frequency, and $f$ is some function. Show more…

Use the wave equation to find the speed of a wave given by $$ y(x, t)=(2.00 \mathrm{~mm})\left[\left(20 \mathrm{~m}^{-1}\right) x-\left(4.0 \mathrm{~s}^{-1}\right) t\right]^{\mathrm{g}-} $$
Use the wave equation to find the speed of a wave given in terms of the general function $h(x, t) :$ $$y(x, t)=(4.00 \mathrm{mm}) h\left[\left(30 \mathrm{m}^{-1}\right) x+\left(6.0 \mathrm{s}^{-1}\right) t\right]$$
