The Formula
The speed of a wave is calculated using the following formula:
* Speed (v) = Wavelength (λ) x Frequency (f)
Applying the Formula
1. Wavelength (λ): 0.2 meters
2. Frequency (f): 1.5 Hz
3. Speed (v) = 0.2 m x 1.5 Hz = 0.3 meters per second (m/s)
Therefore, the speed of the wave is 0.3 meters per second.
