This is in the 2nd harmonic

The wavelength of the harmonic is λ=66

Explanation:

Given data

length= 66cm antinodes= 2

1.To find the harmonic

We have the formula,

No of antinodes= No of harmonic

2=2

This is in the 2nd harmonic

2.The wavelength of the harmonic

We have the formula,

λ=2L/n=2 66/2

λ=66

The wavelength of the harmonic is λ=66
