detailing how sound waves travel through air, the effects of temperature on sound speed, and the phenomenon of refraction. It describes the anatomy of the human ear, how sound is transmitted and ...

Sound waves travel at 1,500 m/s in water. The time between sending and receiving a sonar sound pulse that detects a submarine on the seabed is 0.12 s. Calculate how far below the ship the ...

Through experiments using echoes, beams of sound, and various setups, the film illustrates the principles of reflection, refraction, interference, and standing waves. It confirms that sound ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens.
