Correct Option: E

Correct Answer: Option E

        Comparing y = 10Sin\( (1000\pi t - \frac{\pi x}{34} ) \\

\text{With } y = a \text{Sin }(net - kx)\

K = \frac{\pi}{34}, \text{and phase difference}\

J = KAC = \frac{\pi}{34} \times 1.53rad.\

\text{But} \pi rad = 180^0 \

\text{Therefore } \frac{1.53rad}{34} = \frac{1.53 \pi}{34} \times \frac{1}{\pi} \times 180^0 \

=8.1^0 )
