Given :
A rope 6m long is fixed at one end, the other end is attached to a light string so that it is free to move.
The speed of waves on the rope is 18 m/s.
To Find :
The frequency of the second harmonic.
Solution :
We know, for second harmonic wave :
Wavelength = Length of rope
Now, we know frequency is given by :
Therefore, the frequency of the second harmonic is 3 s⁻¹.
Yes very very fast needs to be on time
Answer:
-65.6 m is the answer.
Explanation:
Brainly deleted my answer even though you got it correct, so this is just a repost.
Answer:
D) 1000 m/s
Explanation:
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
