Sound Waves

Master sound waves! Learn about vibrations, speed, pitch, and analyze wave diagrams in this engaging science worksheet.

What is Sound? Use the video to help you complete the questions. SoundClick on the blank and select the correct term. Sound is created by vibrations that produce waves of energy that move through matter. Sound waves are longitudinal waves because they move back and forth in compressional pulses. Sound waves are mechanical waves because they must have a medium (matter) to travel through. Sound waves travel through all forms of matter. The speed of sound depends on the type of matter it travels through. Sound travels fastest through solids because of the tightly packed matter. Speed of Sound Look at the graph above. Which substance does sound travel through the FASTEST? glass iron air oxygen According to the table, which phase of matter does sound travel the most QUICKLY through? solid liquid gas Look at the graph above. Which substance does sound travel through the SLOWEST? iron cork oxygen glass According to the table, which phase of matter does sound travel the most SLOWLY through? solid liquid gas Sound Wave Properties Definitions Match the vocab word on the left to the definition on the right. Click on the entire box on each side. pitch how HIGH or LOW a sound is loudness how well a sound can be heard ( like volume) reflection the bouncing of sound off of a surface absorption the disappearance of a sound wave into a surface sound wave a longitudinal wave that is caused by vibrations traveling through a medium Sound Wave Properties The pitch of a sound wave is determined by the frequency of the wave. The loudness of a sound wave is determined by the amplitude of the wave. Sound Wave Diagrams Identify the PITCH and LOUDNESS of WAVE A when compared to the other waves. high pitch, loud sound low pitch, loud sound high pitch, soft sound low pitch, soft sound Identify the PITCH and LOUDNESS of WAVE B when compared to the other waves. high pitch, loud sound low pitch, loud sound high pitch, soft sound low pitch, soft sound Identify the PITCH and LOUDNESS of WAVE C when compared to the other waves. high pitch, loud sound low pitch, loud sound high pitch, soft sound low pitch, soft sound Identify the PITCH and LOUDNESS of WAVE D when compared to the other waves. high pitch, loud sound low pitch, loud sound high pitch, soft sound low pitch, soft sound The image above has a _ frequency and _ amplitude? low frequency amplitude high frequency amplitude The image above has a _ frequency? high low
