A velocity and wavelength
Explanation:
When a periodic wave travels from one medium to another, its velocity and wavelength changes in the process.
A periodic wave is a wave with repeating pattern.
- When a wave crosses different medium with different densities, their velocity and wavelength changes.
- This implies that wave causes disturbances in different ways.
- This change in wavelength and velocity as a wave crosses two medium is known as refraction.
- When a wave moves from a less dense medium to a denser one, the velocity reduces and the wavelength increases.

It is dangerous to stand close to railroad tracks when a rapidly moving commuter train passes. Explain why atmospheric pressure would push you toward the moving train. Water pressure inside a hose nozzle can be less than atmospheric pressure due to the Bernoulli effect.
