Frequency
What unit is frequency measured in?

Light waves are electromagnetic and can travel through a vacuum; sound waves are mechanical and need a medium.
What happens to the sound you hear when the amplitude of the wave increases?

Bonus: What kind of wave moves the medium in the same direction as the wave?

They would be much smaller or stop entirely, because wind is what usually transfers energy to water to create waves.
Random: What is Lindleys fav color?

Why can you hear someone talking through a wall, but you can’t see them?

Bonus: Which travels faster: sound or light?
Light
