Wave type: We're talking about longitudinal waves. Imagine a slinky toy being pushed and pulled back-and-forth. That's somewhat how these waves move!
Particle Movement: These particles wiggle back and forth parallel to the tube's central axis (not side-to-side like crazy dancers, but straight up and down like they're doing the cha-cha slide!).
Journey to the End: These waves bravely travel all the way up to the closed end of the tube.
In our visual: They're moving to the right (like they've seen something super exciting there 🍕).
Hitting the Wall: But, oh no! The closed end is like a brick wall. Those particles can't move any further along the axis. It's like running into a dead-end in a maze. 🌽
The Great Turnaround: Because they can't pass through, they must do a U-turn! They reflect and move away from the end.
Perfect Mirror Effect: The reflected wave is the exact opposite of the incident wave, and they cancel each other out right at the boundary. It's like singing a note and hearing an echo that silences your voice! 🎤
Gas assumptions in our pipe party 🎈
Default Guest: When we talk about the gas in the pipe, think of air (like what you blow into birthday balloons). 🎈
Party Crashers: But sometimes, there's a different gas inside. This means...
The speed of sound will dance to a different beat depending on the gas, the room's temperature, and the pressure. 🌡️
The relationship (or the constant of proportionality) between frequency (how fast the party is happening) and wavelength (the length of each dance move) will be different!
