Wave speed can change a lot based on what it's moving through. Here are some key reasons why it varies:
Density: In thicker things, like water, sound travels faster than it does in air.
Elasticity: When a material is more stretchy, waves can move through it faster. For example, sound moves quickly in steel but is slower in rubber.
Temperature: For sounds, if things get hotter, they can speed up. This is because the tiny particles are moving around more.
To sum it up, there's an easy formula to remember:
Wave Speed = Wavelength × Frequency
This means if one part changes, then the wave speed changes too!
