Answer:
0.75Hz
Explanation:
Given parameters:
Speed of the wave = 3m/s
Wavelength = 4m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is given by the expression below:
Speed = frequency x wavelength
Frequency = [tex]\frac{Speed }{Wavelength}[/tex] = [tex]\frac{3}{4}[/tex] = 0.75Hz
