Answer:
Wave speed = 30 meter per second
Explanation:
Frequency of the wave is given to be 100 Hz
Wavelength of the wave is given to be 0.30 m
Now, we need to find the speed of the wave.
Wave speed is given by the formula :
Wave speed = Frequency × Wavelength
⇒ Wave speed = 100 × 0.30
⇒ Wave speed = 30 meter per second
