Problem

A wave travelling along the positive

x

-axis is represented by

y = A\sin(12\pi x - 360\pi t)

. Event P occurs at

x_1 = 0.10\,\text{m}

and

t_1 = 0.002\,\text{s}

, while event Q occurs at

x_2 = 0.55\,\text{m}

and

t_2 = 0.003\,\text{s}

. What is the phase difference

\bigl(\varphi_Q - \varphi_P\bigr)

between the two events? (a)

5.76\pi\,\text{rad}

(b)

5.04\pi\,\text{rad}

(c)

4.68\pi\,\text{rad}

(d)

5.40\pi\,\text{rad}
