Answer:
Explanation:
From the question we are told that:
Frequency of 3rd harmonics 
Frequency of 5th harmonics 
Generally the equation for Wavelength at 3rd Harmonics is mathematically given by
Therefore
Generally the equation for Wavelength at 1st Harmonics is mathematically given by
Therefore
Generally the equation for the frequency of the first harmonic is mathematically given by
-- Well first of all, the waves are <em>transverse waves</em>. The fibers in the rope, and the hand that generates the waves, are moving up and down, but the wave is moving to the right, towards the wall. These directions are perpendicular.
-- Later on, after the waves reflect from the wall and travel back toward the hand, there are going to be <em>standing waves</em> on the rope. But this is probably beyond the scope of the question.
