A wave travels a distance of 60cm in 3s. The distance blw successive crests of thd wave is 4cm. What is the frequency?
wave velocity=.6m/3s=.2m/s
lambda=.04m
f*lambda=v
f=(.2)/.04 hz=5hz
To find the frequency of a wave, we can use the formula:
Frequency = Speed / Wavelength
Given information:
- Wave distance: 60 cm
- Time taken: 3 seconds
- Distance between successive crests: 4 cm
First, let's find the speed of the wave using the equation:
Speed = Distance / Time
Speed = 60 cm / 3 s
Speed = 20 cm/s
Next, we need to find the wavelength. The distance between successive crests is the wavelength. In this case, the distance between successive crests is given as 4 cm.
Wavelength = 4 cm
Now, we can substitute the values of speed and wavelength into the formula for frequency:
Frequency = Speed / Wavelength
Frequency = 20 cm/s / 4 cm
Frequency = 5 Hz
Therefore, the frequency of the wave is 5 Hz.
