Students will learn how sound is produced and how it travels through the air to then register a signal in the brain.
Be amazed by how different frequencies of sound can split the grains into different patterns. (You may want to turn down the volume before watching this video.)
This study guide gives an overview of mechanical waves and the characteristics of transverse waves and longitudinal waves. It also looks at wave interaction: interference (constructive and destructive), beat frequency, standing wave, resonance, and the Doppler effect.
