Ääniaalloilla

Ääniaalloilla, or sound waves, are mechanical waves that propagate through a medium, such as air, water, or solids. They are generated by the vibration of a source, such as a speaker or a human voice, and travel through the medium by causing particles to vibrate. Sound waves are characterized by their frequency, which determines the pitch of the sound, and their amplitude, which determines the loudness. The speed of sound waves depends on the properties of the medium, with sound traveling faster in solids than in liquids and gases. Sound waves can be reflected, refracted, and diffracted, and they can also interfere with each other, leading to phenomena such as resonance and beats. Sound waves are used in a wide range of applications, including communication, music, and medical imaging.
