What are sound waves?
Sound waves are vibrations that move through materials like air, water, or solids, and we can hear them when they reach our ears.
What materials can sound waves travel through?
Sound waves can travel through air, water, and solid objects, as they need a material to move through.
What are the main features of sound waves?
The main features of sound waves include how high or low the sound is (frequency), the distance between waves (wavelength), how loud the sound is (amplitude), and how fast the sound travels.
What does frequency mean in sound?
Frequency means how many times sound waves happen in one second, measured in Hertz (Hz). It affects how high or low the sound is.
