Determination of sea depth and fish shoals by echo is one of the most practical applications of sound waves. Ships and fishing vessels use echo-sounding technology to measure ocean depth, locate underwater obstacles, and...
Uses and laws of reflection of sound waves are among the most important concepts in physics because they explain how sound travels, bounces off surfaces, and is applied in medicine, engineering, navigation, and everyday...
There are two types of sound waves, which are audible sounds and non-audible sounds. The audible sounds, such as the sonic waves, and the non-audible sounds, such as the ultrasonic waves and the infrasonic...
Mechanical waves are the waves that propagate through a material medium (the solid, the liquid, or the gas) at a wave speed that depends on the properties of that medium. The mechanical waves need...
