A tuning fork of frequency

256\,\text{Hz}

is struck and first held in air, then immersed in water. (i) If the speed of sound in air is

340\,\text{m/s}

, calculate the wavelength of the sound produced in air. (ii) The speed of sound in water is

1480\,\text{m/s}

. Calculate the wavelength of the same sound in water.
