waves of frequency 20 hz are generated along spring. the distance between successive crests and troughs is 0.45m
What is your question?
you can determine the speed of the wave from the wave equation:
frequency*wavelength=speed
20hz*.90m=18m/s
V=DF
V=O.45×20hz
V= 9m/s
To find the speed of the waves generated along the spring, you can use the formula:
Speed = Frequency x Wavelength
Where:
- Speed is the speed of the wave.
- Frequency is the number of cycles or oscillations per second, measured in hertz (Hz).
- Wavelength is the distance between two successive crests or troughs of the wave.
Given that the frequency of the waves is 20 Hz and the distance between successive crests and troughs is 0.45 m, we can substitute these values into the formula:
Speed = 20 Hz x 0.45 m
Calculating the expression:
Speed = 9 m/s
Therefore, the speed of the waves along the spring is 9 m/s.
