Aquí tienes la solución al Ejercicio N°1:

  1. La relación entre la velocidad de una onda (vv), su frecuencia (ff) y su longitud de onda (λ\lambda) está dada por la fórmula

    v=λfv = \lambda f

  2. Para encontrar la longitud de onda (λ\lambda), reorganizamos la fórmula

    λ=vf\lambda = \frac{v}{f}

  3. Sustituimos los valores dados

    v=343 m/sv = 343 \text{ m/s} f=7000 Hzf = 7000 \text{ Hz} λ=343 m/s7000 Hz\lambda = \frac{343 \text{ m/s}}{7000 \text{ Hz}}

  4. Realizamos el cálculo

    λ=0.049 m\lambda = 0.049 \text{ m}

    La longitud de onda del sonido en el aire es:

    0.049 m0.049 \text{ m}
