A device emits a sound wave in helium gas which then travels into standard air of the same temperature. If the speed of sound in helium is about three times the speed of sound in standard air, which of the following is true? The frequency of the sound is unchanged as the wave travels from helium to standard air while the wavelength increases. The frequency of sound decreases as the wave travels from helium to standard air while the wavelength...
