Show that the following functions satisfy the wave equation: a) y(x,t) = (x + vt)^2 b) y(x,t) = ln(x - vt)
Sri K.
Consider two wave functions $y(x, t)=0.30 \mathrm{cm} \sin \left(3 \mathrm{m}^{-1} x-4 \mathrm{s}^{-1} t\right)$ $y(x, t)=0.30 \mathrm{cm} \sin \left(3 \mathrm{m}^{-1} x+4 \mathrm{s}^{-1} t\right) .$ Write a wave function for the resulting standing wave.
