What Is Sound?: Frequency and Pitch

The video tutorial explores the differences in sounds produced by various animals, focusing on the concept of frequency. Frequency, measured in Hertz, is the number of complete waves passing a point in a given time and is a key factor in sound variation. The tutorial explains how frequency affects pitch, with higher frequencies resulting in higher pitches. It also covers the range of frequencies humans can hear, from 20 to 20,000 Hertz, and notes that some animals, like dolphins and dogs, can detect even higher frequencies.
