    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
