Describing a Sound Wave
Physics · High School (9–10), General · Wave Motion, Sound Waves and Hearing
FreeCh 5 · 2/3
A drum and a flute can play at the same loudness, but we never confuse them. A whistle is high and a bass drum is low. In this course we describe a sound with its wavelength, frequency and amplitude, and we use the wave equation to connect them with the speed.
