Dolphins emit sound waves that they use for communication. If the wavelength of an emitted sound wave is 3.0 cm and the speed of sound in the medium is m/s, what is the period of the sound wave?
A dolphin makes sounds in air and in seawater. Given that the temperature of air is , what is the ratio of the wavelength of a sound in air to its wavelength in seawater? Use a value of 1.225 kg/m3 for the density of air and kg/m3 for the density of seawater.
What is the period of the wave?
What is the wavelength of the sound wave?
