25 Οκτ 2020 · Language: English (en) ID: 446263. 25/10/2020. Country code: IN. Country: India. School subject: Science (1061951) Main content: Sound (2011479) From worksheet author: Properties of sound.
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 __~1.7__ cm. The pitch of a sound is directly related to the __frequency__ of the sound wave.
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.
