Asinusoidal wave has the following wave function: y(x, t) = (2.5 m) sin((3.0 m ) x - (24 s-')t + tt/2] what is the frequency of this wave? (a) 0.48 hz, (b) 3.0 hz, (c) 3.8 hz, (d) 12 hz, (e) 24 hz.

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.

step-by-step explanation:

10 - 2.8 = 7.2

2 2/5 = 2.4

7.2 / 2.4 = 3
