Does the equation
`y=+sqrt(16-(2x-t)^(2)`,
(2x-t)lt4 or (2x-t)gt-4`,
=0,otherwise
represent a wave? If yes, then find the amlityde and the phase velocity.

Explanation

To determine if the equation \( y = \sqrt{16 - (2x - t)^2} \) represents a wave, and to find its amplitude and phase velocity, we can follow these steps:

### Step 1: Check if the equation represents a wave
A function \( y \) is said to represent a wave if it can be expressed in the form \( y = f(x - vt) \) or \( y = f(x + vt) \).

In our case, we have:
\[
y = \sqrt{16 - (2x - t)^2}
