• Imagine: You're at a concert. The music is blasting. You feel the vibe in the air. The wave's journey is what we're mapping!
• Y-axis: Displacement (like a dancer's movement up and down)
• X-axis: Distance along the wave (like the concert stage length)

Quick Facts:

• Longitudinal Wave: Displacement and distance along the wave are like best friends, always side by side (parallel). 🚂
• Transverse Wave: They're more like frenemies, at 90°. Think of a snake moving sideways. 🐍

Real-life example: Ever jumped on a trampoline? When you bounce, you make transverse waves! Your high jump represents a peak in the graph.

Displacement-time graph

• 🎯 Tells you amplitude (how high the wave goes) and wavelength (distance between two peaks).
• 🚫 Doesn't directly spill beans about time period or frequency.

• Transverse is like seeing a snake slithering side to side.
• Longitudinal is like watching dancers move back and forth in a line dance.

Fun Bit: In longitudinal waves, where the particles are squished together, we get a compression (like a traffic jam). Where they’re spread out? That’s a rarefaction (like the open road on an early morning).

• Real waves have a start and end in space and time. No infinite waves here! 📏
• If a wave goes through n cycles, its time is nT, and its length is nλ (n times the wavelength).

For Dummies: If a wave had a party for 5 hours (nT) and each song played was 3 minutes long (λ), then the total party time would be the number of songs multiplied by their length!
