Question 1 Report
The distance between the successive crests of a wave travelling at 20ms-1 is 25cm. Calculate the frequency of the wave
Answer Details
The formula to calculate the frequency of a wave is:
frequency = wave speed / wavelength
Where the wavelength is the distance between two successive crests of a wave.
In this problem, the wave speed is given as 20ms^-1 and the wavelength is given as 25cm. However, we need to convert the wavelength to meters since the wave speed is also given in meters per second.
wavelength = 25cm = 0.25m
Now we can substitute the values in the formula and solve for frequency:
frequency = 20ms^-1 / 0.25m
frequency = 80Hz
Therefore, the frequency of the wave is 80Hz.
