(a) $\lambda = 0.277~m$ (b) $\lambda = 0.504~m$ (c) $\lambda = 0.277~m$

Work Step by Step

(a) We can find the wavelength: $\lambda = \frac{v}{f}$ $\lambda = \frac{341~m/s}{1231~Hz}$ $\lambda = 0.277~m$ (b) When a wave travels from one medium into another medium, the frequency does not change. We can find the wavelength: $\lambda = \frac{v}{f}$ $\lambda = \frac{620~m/s}{1231~Hz}$ $\lambda = 0.504~m$ (c) We can find the wavelength: $\lambda = \frac{v}{f}$ $\lambda = \frac{341~m/s}{1231~Hz}$ $\lambda = 0.277~m$
