Final answer:
Sound is the movement of molecules that produce sound waves, and the speed of a wave is determined by its frequency and wavelength, explained by physics.
Explanation:
Sound can be informally considered as the movement of molecules through a medium, such as air or water, causing compressions and rarefactions that our ears interpret as sound. This can be seen when a bell rings, creating vibrations in the air that reach our ears as sound waves.
The relationship between speed, frequency, and wavelength is defined by the equation c = λv, where c is the speed of the wave, λ is the wavelength, and v is the frequency. This equation shows how the speed of a wave is determined by its wavelength and frequency.
Physics provides us with a unified way to describe various forms of motion in nature, from the vibrations of molecules producing sound to the electromagnetic radiation of light traveling through space. Understanding these motions helps us explain phenomena like the speed of light in a vacuum and the behaviors of waves in different mediums.
