Problem
A wave is represented by
y
1
=
10
cos
(
5
x
+
25
t
)
y_1 = 10 \cos (5x + 25t)
y
1
=
10
cos
(
5
x
+
25
t
)
where,
x
x
x
is measured in metres and
t
t
t
in seconds. A second wave for which
y
2
=
20
cos
(
5
x
+
25
t
+
π
3
)
y_2 = 20 \cos \left( 5x + 25t + \frac{\pi}{3} \right)
y
2
=
20
cos
(
5
x
+
25
t
+
3
π
)
interferes with the first wave. Deduce the amplitude and phase of the resultant wave.
