Question

3 m/s

4 m
Which of the following is the frequency of the wave?
a) 0.75 Hz
b) 1.33 Hz
C) 1.5 Hz
d) 6.0 Hz

Answer 1

0.75Hz

Step-by-step 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 =
`(Speed )/(Wavelength)` =
`(3)/(4)` = 0.75Hz
