Waves come in different types, and they act differently depending on the material they are in. Let's break it down!

1. Transverse Waves:

• What They Need: These waves need a solid material, like a rope.
• How They Move: The particles in the material move up and down or side to side while the wave goes forward.
• Example: Light waves are a great example. They can even travel through empty space!

2. Longitudinal Waves:

• What They Need: These waves can move through solids, liquids, and gases.
• How They Move: The particles in these waves push and pull back and forth in the same direction as the wave is moving.
• Example: Sound waves are a perfect example of longitudinal waves.

The speed of these waves can be affected by the material they travel through. There's a neat formula for this: wave speed = frequency × wavelength. This shows how these waves change and interact with their surroundings, which is really interesting!
