Sounds
Sophomore / 10th grade
Physics
Sound is a type of mechanical wave that travels through various media, such as air, water, and solids, produced by vibrating objects. When an object vibrates, it creates fluctuations in air pressure, forming compressions (where particles are close together) and rarefactions (where particles are spread apart). These pressure changes propagate through the medium as sound waves. Sound is characterized by properties like frequency, amplitude, wavelength, and speed. Frequency determines the pitch of ...
