🔊 What is sound?

Sound is something you hear with your ears! 👂 When you clap your hands, sing a song, or a dog barks, that's sound. It travels through the air like tiny waves that tickle your ears. 🎵

Imagine throwing a pebble into water and seeing ripples. Sound moves like those ripples, but you can't see them!

Sound is a type of energy made by vibrations! 🎤 When something moves back and forth quickly (like a guitar string or your vocal cords), it pushes air molecules together, creating sound waves. These waves travel to your ears, and your brain understands them as sounds.

How does it work?

• Vibrations create waves (like shaking a slinky!).
• Waves move through air, water, or even solids.
• Your ears catch the waves and send signals to your brain.

Sound is a mechanical wave produced by vibrating objects that propagates through a medium (air, water, solids). Here's the science behind it:

Key concepts:

• Frequency (pitch): Measured in Hertz (Hz). High frequency = high-pitched sounds.
• Amplitude (loudness): Bigger vibrations = louder sounds.
• Speed: Depends on the medium (~343 m/s in air at 20°C).

Sound waves are longitudinal waves where particles move parallel to the wave direction. Your outer ear funnels waves into the eardrum, which vibrates tiny bones that send signals to the brain.
