The speed of a wave is 2 m/s, and its wavelength 0.4 meters. What is the period of the wave? (1 point)
• 0.2 seconds
• 2 seconds
• 5 seconds
• 0.8 seconds
The speed of a wave is given by the equation:
speed = wavelength / period
Rearranging the equation, we can solve for the period:
period = wavelength / speed
Substituting the given values:
period = 0.4 meters / 2 m/s
period = 0.2 seconds
Therefore, the period of the wave is 0.2 seconds.
