Problem

A wave source produces 600 oscillations in 15 s while the wave travels

450\,\text{m}

in the same time. The wave then enters another medium where its speed becomes

24\,\text{m/s}

while the frequency remains unchanged. Find the wavelength of the wave in the second medium. a)

0.75\,\text{m}

0.50\,\text{m}

0.60\,\text{m}

0.94\,\text{m}
