Sound: Pitch and Frequency

The video tutorial explains how sound frequency affects the differences in sounds, such as those made by animals, and introduces the concept of pitch. It describes how pitch is related to frequency and demonstrates this using a piano. The tutorial also covers the human hearing range, the measurement of frequency in hertz, and the ability of some animals to hear ultrasonic sounds. Applications of ultrasonic waves, such as sonar, are discussed, along with infrasonic waves and their examples.

Describe how sonar technology works and its applications.

Explain what infrasonic waves are and provide an example of how they are produced.
