Answer:
Frequency of the wave is 3.8 hertz.
Explanation:
It is given that, the sinusoidal wave has following wave equation as :
The general equation for the sinusoidal wave is :
Where
A is the amplitude
k is the constant
is the angular frequency
is the phase difference
Since,
or
f = 3.8 Hz
So, the frequency of the wave is 3.8 hertz. Hence, this is the required solution.
