Properties of Sound Waves Read from Lesson 2 of the Sound and Music chapter at The Physics Classroom: http://www.physicsclassroom.com/Class/sound/u11l2a.cfm
1. Sound waves are longitudinal waves. 2. As the teacher talks, students hear the voice because particles of air move from the mouth of the teacher to the ear of the student. 3. Sound waves are mechanical waves. 4. All sound waves are produced by a vibrating object. 5. A sound wave does not consist of crests and troughs. 6. Mac is talking to Kate.
A sound wave with its characteristic pattern of compressions and rarefactions is shown below. A centimeter ruler is included below the pattern. The wavelength of this sound wave is _____ cm. The pitch of a sound is directly related to the _________ of the sound wave.
Sound. 7th Grade Science Worksheets and Answer key, Vocabulary Sets. Covers the following skills: apply properties and characteristics of waves to analyze sound. Analyze the transfer of energy in a variety of situations (e.g., the production of heat, light, sound. Homework. U.S. National Standards.
Summary notes, revision videos and past exam questions by topic for CAIE IGCSE Physics Topic 3 - Properties of Waves including Light and Sound.
Sound is a waveform made from vibrating matter. The sound wave travels through matter—especially air—in a straight line. When the wave hits a different material, some of it is reflected, absorbed and transmitted through the material. In the case of a sound wave in air hitting a solid wall, most of the sound is reflected.
Properties of Sound. Frequency: The number of vibrations per second. It is measured in Hertz (Hz). Amplitude: The measure of the energy of the sound wave, which determines the loudness of the sound. It is measured in decibels (dB). Wavelength: The distance between two consecutive compressions or rarefactions in a sound wave.
