Supersonic aircraft produce a shock wave called a “sound boom”. This occurs when the aircraft travels faster than the speed of sound, creating a sudden increase in pressure and temperature. The resulting shock wave is perceived on the ground as ...

The instrument used to identify and draw sound waves is called a “sonar”. Sonar stands for Sound Navigation and Ranging. It emits sound waves into water and detects the echoes bounced back from objects, helping in navigation, communication, and underwater ...
Sound does not pass through vacuum. Sound waves require a medium such as air, water, or solid materials like steel to propagate because they travel through the mechanical vibration of particles in the medium. In vacuum, where there is an ...
Sound waves cannot propagate in vacuum. Sound requires a medium (such as air, water, or solid materials) for transmission because it involves the mechanical vibration of particles in the medium.
Sonography is a biological method that uses ultrasonic sound. It involves the use of high-frequency sound waves to create images of the inside of the body. These sound waves, beyond the range of human hearing, are transmitted into the body ...
