Waves: What is Sound? & Properties of Sound Videos

Discover what sound is and its properties! Learn about wave types, frequency, amplitude, and how sound travels.

Type your name. Name _ Instructions: You have two short videos on sound to watch for this assignment. The first video is a Brainpop video and the second video is a Studyjams video. There are questions you have to answer after watching each video. The last several questions are review from previous assignments to see if you learned the information.Each instruction and question has a read aloud feature. If you choose to use the read aloud feature, click on the play button to have each question read aloud to you. Brainpop Sound Video Watch the video on sound and answer the questions that follow. The answers to the questions are in the video. You can use the pause button to stop and start the video, watch the video more than once, and use the red dot to slide the video forward and backward if needed to find answers. How are ocean waves different from sound waves? Ocean waves are transverse waves, sound waves are longitudinal waves. Ocean waves are longitudinal waves, sound waves are transverse waves. Ocean waves are electromagnetic waves, sound waves are mechanical waves. Ocean waves are mechanical waves, sound waves are electromagnetic waves. What are you doing when you're making sound? causing photons to travel causing air molecules to vibrate causing electromagnetic waves to radiate causing air pressure to drop What is compression? When air molecules move apart from one another. When air molecules collide with one another. When air molecules become packed tightly together. When air molecules move around freely. What would a wave with a low amplitude sound like? It would sound quiet. It would sound loud. It would sound tinny. It would sound deep. What is the relationship between frequency and sound? Frequency affects a sound's volume. Frequency affects a sound's amplitude. Frequency affects a sound's loudness. Frequency affects a sound's pitch. Which of these does sound travel the fastest through? steel water air rock Which of these would absorp the most sound? Studyjams Sound Video Watch the video on sound and answer the questions below. You can use the pause button, slide the video forward or backward to find answers and watch the video more than one time to hear the answers to the questions. What role does energy play in sound? Sound waves have nothing to do with energy. Sound waves carry energy. Energy is present in loud sounds only. Energy is present in high-pitched sounds but not in low-pitched sounds. What is an echo? the number of sound waves in a second the loudness or softness of a sound sound waves that bounce off a surface the highness or lowness of a sound What sort of frequency do high-pitched sounds have? high low medium no frequency What does volume measure? the speed of sound the frequency of sound the highness or lowness of sound the loudness or softness of a sound Which two aspects of sound go together? pitch and frequency decibels and pitch pitch and volume amplitude and pitch What does amplitude measure? frequency volume pitch echoes The next few questions are review questions to see if you learned this from previous lessons on waves.How can you hear sound if you are in a separate room and the sound is coming from a different room? refraction reflection absorption diffraction What unit of measurement is used to measure pitch? hertz decibels amplitude volume What unit of measurement is used to measure volume? hertz decibels frequency pitch
