Understanding Sound: Waves, Volume, Pitch, and Decibels

Explore the fascinating world of sound with us! Discover how sound is created through vibrations when two objects touch and how it travels in waves. Learn about the concepts of volume, which measures how loud or soft a sound is, and pitch, determining how high or low a sound can be. We will also discuss decibels, the measurement of sound intensity, and frequency, the number of vibrations per second. Test your knowledge with our quiz! Join us as we dive into the future of sound!
