Problem

For a travelling wave described by

y = 4 \sin\!\bigl(40\pi t - \dfrac{2\pi x}{0.50}\bigr)

(SI units), find the phase difference (in degrees) between the events: P

(x = 0.30\,\text{m},\, t = 0.010\,\text{s})

and Q

(x = 0.55\,\text{m},\, t = 0.012\,\text{s})

. State whether the two events are in phase, in opposite phase, or neither.
