Consider the wave equation $y =10\sin(7(x-50t))$. What does the number 10 in the equation represent?

The general equation of a wave is $Y=A \sin2πλ(vt±x)$. Where $A$ is the amplitude, $λ$ is the wavelength and $v$ is the velocity of the wave. The number $10$ in $y =10\sin(7(x-50t))$ therefore stands for the amplitude of the wave.
