A simple harmonic wave is expressed by equation,
`y=7xx10^(-6)sin(800pit-(pi)/(42.5)x)`
where y and x are in cm and t is in second.
Calculate (i) amplitude (ii) frequency
(iii) wavelength )
(iv) wave velocity
(v) Phase difference between two particles separated by 17.0cm.

Explanation

To solve the given problem step by step, we will analyze the wave equation and extract the required parameters.

Given wave equation:
\[ y = 7 \times 10^{-6} \sin(800 \pi t - \frac{\pi}{42.5} x) \]

### Step 1: Calculate Amplitude
The amplitude \( A \) of a wave is the coefficient of the sine function in the wave equation.
