5. If a wave has a wavelength of 20m and a speed of 100 m/s, what is the period of the oscillation?
v = wavelength / period
100 = 20 / period
100*20 = periodperiod = 20 / 100
2000 s = period
OR
period = 20 / 100
period = 0.2 s
I don't know which one is correct, please help?!
v=w*f=w/t
T=w/v=20/100 sec
To find the period of the oscillation, you can use the equation:
speed = wavelength / period
Given that the wave has a wavelength of 20m and a speed of 100 m/s, you can rearrange the equation to solve for the period:
period = wavelength / speed
Substituting the given values:
period = 20m / 100 m/s
Now, you can simplify the equation:
period = 0.2 s
So, the correct answer is 0.2 seconds.
To find the period of the oscillation, you can use the formula:
period = wavelength / speed
In this case, the given wavelength is 20m and the speed is 100 m/s.
So, you can substitute these values into the formula to find the period:
period = 20m / 100 m/s = 0.2 s
Therefore, the correct answer is a period of 0.2 seconds (s).
