Answer:
Amplitude, A = 0.0205 m
Frequency, f = 0.636 Hz
Wavelength, 18.84 m
Explanation:
Given that,
Speed of the wave along a taught string, v = 12 m/s
A fixed point on the string oscillates as a function of time according to the equation :
........(1)
Here, y is the displacement in meters and the time t is in seconds
The general equation of oscillation is given by :
............(2)
On comparing equation (1) and (2) we get :
(a) Amplitude, A = 0.0205 m
(b) Frequency of the wave,

(c) Velocity of the wave is given by formula as :

Since,


Hence, this is the required solution.
