Hanghullámoknál

Hanghullámoknál refers to sound waves in Hungarian. Sound waves are mechanical waves that propagate through a medium, such as air, water, or solids, by causing vibrations of the particles within that medium. These vibrations travel outwards from the source of the sound as a series of compressions and rarefactions. Compressions are regions where the particles are momentarily closer together, increasing the pressure, while rarefactions are regions where the particles are spread further apart, decreasing the pressure.

The frequency of a sound wave determines its pitch. Higher frequencies correspond to higher pitches, and lower frequencies correspond to lower pitches. The human ear can typically detect sound waves within a specific frequency range, generally from about 20 Hertz (Hz) to 20,000 Hz. Sounds with frequencies below this range are called infrasound, and those above are called ultrasound.

The amplitude of a sound wave is related to its loudness or intensity. Larger amplitudes correspond to more energetic vibrations and thus louder sounds. The speed at which sound waves travel depends on the properties of the medium they are passing through, such as its density and elasticity. For example, sound travels faster in solids than in liquids, and faster in liquids than in gases. When sound waves encounter a boundary between two different media, they can be reflected, refracted, or diffracted. These phenomena are fundamental to how we perceive and interact with the auditory world.
