Problem
The equation of a travelling wave is
y
(
x
,
t
)
=
0.02
sin
(
x
0.05
+
t
0.01
)
m
y(x, t) = 0.02 \sin\left(\frac{x}{0.05} + \frac{t}{0.01}\right) \text{ m}
y
(
x
,
t
)
=
0.02
sin
(
0.05
x
+
0.01
t
)
m
Find (a) the wave velocity and (b) the particle velocity at
x
=
0.2
m
x = 0.2 \text{ m}
x
=
0.2
m
and
t
=
0.3
s
t = 0.3 \text{ s}
t
=
0.3
s

cos
θ
=
−
0.85
\cos \theta = -0.85
cos
θ
=
