The time taken for the sound wave to return to the receiver would INCREASE. Reason being: Sound travels faster in denser mediums like water compared to air. Therefore, when sound waves travel through air, which is less dense, they take longer to return to the receiver due to reduced speed.
The frequency of the sound REMAINS THE SAME. Reason being: Frequency is determined by the source of the sound and does not change when it travels from one medium to another. Whether the sound travels through air or water, the frequency remains constant, although its speed and wavelength may vary.
