Answer:
the wave represents the second harmonic.
Explanation:
Given;
length of the cord, L = 64 cm
The first harmonic of a cord fixed at both ends is given as;
The wavelength of a standing wave with two antinodes is calculated as follows;
L = N—> A —–> N + N —-> A —–> N
Where;
N is node
A is antinode
L = N—> A —–> N + N —-> A —–> N = λ/2 + λ/2
L = λ
The harmonic is calculated as;
Therefore, the wave represents the second harmonic.
L = λ
