Any very hard very smooth surface.
Because when it reflects off of the rarefaction, it tightens causing sound waves to burst.
Sound that reflects is known as an echo. Echoes occur when sound waves bounce off surfaces and return to the listener's ears with a delay, creating a repetition of the original sound. The distance and types of surfaces the sound waves bounce off of can affect the quality and intensity of the reflected sound.
Surfaces that are hard and smooth, such as walls, floors, and ceilings, reflect sound waves effectively. Soft and porous materials, like carpets, curtains, and acoustic panels, absorb sound waves rather than reflecting them.
When a sound reflects, it bounces off a surface and changes direction. The sound wave behaves similarly to light waves reflecting off a mirror. The angle of incidence is equal to the angle of reflection.
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
Pressure waves.
For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal.
wire does it best
Sound waves from a radio typically travel through the air as it is a medium that allows for the propagation of sound waves. Sound waves are generated by the radio transmitter and then travel through the air as vibrations in the form of pressure waves to reach the receiver.
The water will reflect some of the sound, and some will travel downward through the water.
Light and sound waves can both be reflected. Light reflects off of smooth surfaces like mirrors, while sound waves reflect off of hard surfaces like walls or cliffs.
multiple reflection of sound is the process in which sound waves bounces off obstacles and reflects many times before reaching the destination. this is the phenomena that occurs in a stethescope. sound waves reflect through the tube many times before reaching the ears of the doctor
