Answer:
We can use the formula:
speed = distance/time
A. To find the speed of the wave:
speed = distance/time = 209m/0.56s = 373.2 m/s
Therefore, the speed of the wave is 373.2 m/s.
B. To find the wavelength of the wave, we can use the formula:
wavelength = speed/frequency
wavelength = 373.2 m/s / 620 Hz = 0.602 m
Therefore, the wavelength of the wave is 0.602 m.
C. To find the period of the wave, we can use the formula:
period = 1/frequency
period = 1/620 Hz = 0.00161 s
Therefore, the period of the wave is 0.00161 s.
