Sound is the movement of compression waves (longitudinal waves) hitting our ears. These compression waves are alternating high and low pressure areas. The air molecules vibrate back and forth, but don't move. Speakers imitate sounds by pushing air and causing vibrations.
Sound Waves. Sound waves are caused by vibrating particles and are an example of a longitudinal wave. Human ears are specially adapted to hear sound waves and we can make use of certain types of sound waves called ultrasound waves in medicine and echolocation technology.
Study Tips. Understand the relationship between frequency and pitch. Learn how different materials affect the speed of sound. Practice identifying the parts of a wave (crest, trough, wavelength). Explore the effects of amplitude on the perception of loudness. [Sound] Related Worksheets and Study Guides: Sound and light energy Science • Fifth Grade.
