The equation of a stationary wave is represented by
`y=2sin((2pix)/(3))sin(3pit)`
Where y and x are in metre and t is in second. Calculate amplitude, frequency, wavelength and velocity of the component waves whose superposition has produced these vibrations.

Explanation

To solve the problem, we will analyze the given stationary wave equation step-by-step and extract the required parameters: amplitude, frequency, wavelength, and velocity.

### Given:
The equation of the stationary wave is:
\[ y = 2 \sin\left(\frac{2\pi x}{3}\right) \sin(3\pi t) \]

### Step 1: Identify the Amplitude
The amplitude \( A \) of the wave can be determined from the coefficient of the sine function in the equation.
