Problem

A sinusoidal wave of frequency

1200\,\text{Hz}

travels successively through three media A, B and C. The speeds of the wave in the three media are

300\,\text{m\,s}^{-1}

240\,\text{m\,s}^{-1}

and

480\,\text{m\,s}^{-1}

respectively. a. (a) Calculate the wavelength of the wave in each medium. b. (b) Write the ratio

\lambda_{A} : \lambda_{B} : \lambda_{C}
