From the theory we know that:
c = λ / T
f = 1 / T
Where:
c = 3.
/ m (the speed of light)
λ is the wavelengh (in meters)
T is the period (in seconds)
f is the frequency (in Hz)
We were told that:
f = 7.30 . 
And we want to find out the value of λ.
c = λ / T
c = λ . 1/T
Swaping 1/T = f
c = λ . f
λ = c / f
λ = 3 . / 7.30 .
λ = 4.12 
m
Response: 4.12 m = 412 nm

The wave is equation with the given conditions is y = 0.02 cos ( 0 )
<u>Given data</u>
period T= 25.0ms
speed of 30.0 m/s
t = 0
x = 0
transverse position of 2.00cm
speed of 2.0 m/s = v
<h3>writing the wave function </h3>
frequency f = 1 / T
f = 1 / 25
f = 0.04Hz
Angular velocity = ω = 2 * pi * f
ω = 2 * pi * 0.04
ω = 0.251
wave number K = ω / v
k = 0.251 / 2
k = 0.126
The wave equation
y = A cos ( kx + ωt )
this is equivalent to
y = 0.02 cos ( 0.126 * 0 + 0.251 * 0 )
y = 0.02 cos ( 0 )

You should first break up all the distances and directions into vectors and then add all horizontal vectors and verticle vectors.
He goes, 5 + 1 m east = 6m East
3 m north
displacement = root(6^2 + 3^2) = 6.708m
direction = arcTan(verticle/horizontal) = arcTan(3/6) = 26.565 degrees
