the wave motion takes 10 s to complete one full vibration.
17.1 how long does it take for 8 waves to move past a certain point?
17.2 what is the period of the wave motion?
17.3 calculate the wavelength of the wave range
17.4 calculate the frequency of this wave range
17.5 calculate the speed of this wave range
17.1 To find the time it takes for 8 waves to move past a certain point, we can use the formula:
Time = (Number of waves) x (Period)
In this case, the number of waves is 8, and the period is given as 10 seconds. So,
Time = 8 x 10 = 80 seconds
Therefore, it takes 80 seconds for 8 waves to move past the certain point.
17.2 The period of the wave motion is given as 10 seconds.
17.3 To calculate the wavelength of the wave, we can use the formula:
Wavelength = (Wave speed) / (Frequency)
Since the wave speed is not given, we cannot determine the wavelength with the given information.
17.4 To calculate the frequency of the wave, we can use the formula:
Frequency = 1 / (Period)
The period is given as 10 seconds, so
Frequency = 1 / 10 = 0.1 Hz
Therefore, the frequency of this wave range is 0.1 Hz.
17.5 To calculate the speed of the wave range, we can use the formula:
Speed = (Wavelength) x (Frequency)
Since we cannot determine the wavelength with the given information, we cannot calculate the speed of the wave range.
