🔊 What is Sound (in Physics)?

Sound is basically vibrations that travel through a medium (like air, water, or solid stuff) and get to your ears. Your brain then goes, “Oh snap, that’s a sound.”

📦 Key Stuff You Gotta Know:

• Medium: Sound needs something to travel through. No air = no sound. That’s why space is silent, Space Legend. 😎

• Vibrations: It starts with something shaking—like a guitar string or your vocal cords.

• Waves: Sound moves in longitudinal waves, where the particles vibrate back and forth (parallel to the direction of the wave).

📊 Properties of Sound Waves:

PropertyWhat It MeansFrequencyHow many waves per second (measured in Hz). Higher frequency = higher pitch.AmplitudeHow big the wave is. Bigger = louder.WavelengthDistance between waves.SpeedHow fast it travels (depends on the medium).

⚡ Example:

• In air, sound travels around 343 m/s at room temp.

• In water, it’s faster—about 1500 m/s.

• In solids, it’s even faster—depends on the material.

  
  

  ⚡ Speed of Sound – The Basics:

  The speed of sound is how fast a sound wave moves through a medium (air, water, steel, etc.).

  📍In Air (at room temperature, ~20°C or 68°F):

  • Speed = ~343 meters per second (m/s)

  • That's about 1235 kilometers per hour (km/h) or 767 miles per hour (mph)

  🔥 Cool Facts:

  • Higher temperature = faster sound (in air).

  • Sound travels fastest in solids, slower in liquids, slowest in gases.
