Answer on Question #51190, Physics, Mechanics | Kinematics | Dynamics

In the wave equation $y = \frac{\text{asin}(wt + kx)}{\text{the quantity}(wt + kx)}$ represents the symbols have the usual meaning

Answer:

$$y(t, x) = A \cdot \sin(\varphi_0 + \varphi(t) + \varphi(x))$$

A is the amplitude, $\varphi_0$ is the initial phase, $\varphi(t)$ time defined phase, $\varphi(x)$ space defined phase.

And the sum of this phases calls just as phase.

$$\varphi_0 + \varphi(t) + \varphi(x) = \varphi$$

In this problem

$$y(t, x) = A \cdot \sin(wt + kx)$$ $$\varphi = wt + kx$$

It is the phase of the oscillation in this wave at some time at some point of space.
