Question 1 Report
A vibrator causes water ripples to travel across the surface of a tank. The wave travels 50cm in 2s and the distance between successive crests is 5cm. Calculate the frequency of the vibrator
Answer Details
The frequency of the vibrator can be calculated using the formula:
frequency = speed / wavelength
where speed is the speed of the wave, and wavelength is the distance between successive crests.
In this case, we are given that the wave travels 50cm in 2s, which means the speed of the wave is:
speed = distance / time = 50cm / 2s = 25cm/s
We are also given that the distance between successive crests is 5cm, which is the wavelength.
Therefore, the frequency of the vibrator is:
frequency = speed / wavelength = 25cm/s / 5cm = 5Hz
So the correct answer is 5Hz.
