24. A sound wave generated from a tuning fork of single frequency travels from air (with speed of sound 340m/s ) into rock (with speed of sound 1500m/s ). Which statement is true about the wavelength and frequency of the sound as it passes from air to rock?
(A) The frequency of the sound increases and the wavelength increases.
(B) The frequency of the sound increases and the wavelength is unchanged.
(C) The frequency of the sound is unchanged and the wavelength is decreased.
(D) The frequency of the sound is unchanged and the wavelength is increased.
