It increases.

They will travel faster through solid materials and get progressively slower through liquids and gases.

The sound waves of notes with higher pitches have higher frequencies.

It slows down.

It changes direction.

A sound wave is a type of mechanical wave that is created by vibrating objects and travels through a medium such as air, water, or solids.

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Amplitude is the height of the wave, which determines the loudness of the sound; higher amplitude means louder sound.

Shorter wavelengths correspond to higher pitches, while longer wavelengths correspond to lower pitches.

Refraction is the bending of light as it passes from one medium to another, changing its speed.
