The speed of sound is dependent on the tissue through which it is traveling. As sound travels from one tissue to another and changes speed, this change in speed is accounted for by a reciprocal change in wavelength (allowing frequency to remain unchanged).\u003c/p\u003e","id":2784,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2828","nextQuestionPath":"/articles/ultrasound-frequencies/questions/2783","relatedArticles":[{"id":67529,"title":"Attenuation (ultrasound)","link":"/articles/attenuation-ultrasound?lang=us"}],"alsoUsedIn":[{"id":1608,"kind":"RestrictedPage","title":"Page 1608 (in no courses)","link":"https://radiopaedia.org/admin/restricted_pages/1608"},{"id":1972,"kind":"Course","title":"Imaging Physics: Ultrasound Peer Review - page 1972","link":"https://radiopaedia.org/courses/imaging-physics-ultrasound-peer-review/pages/1972"},{"id":1972,"kind":"Course","title":"Imaging Physics: Ultrasound - page 1972","link":"https://radiopaedia.org/courses/imaging-physics-ultrasound/pages/1972"}],"stem":"\u003cp\u003eAs sound travels from one tissue to another, which property will remain unchanged?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2784"}],"attemptsPercentages":[{"alternativeId":"13584","percentage":3},{"alternativeId":"13585","percentage":80},{"alternativeId":"13586","percentage":8},{"alternativeId":"13588","percentage":8},{"alternativeId":"13587","percentage":2}],"promptToLogin":false,"questionManager":false,"articleId":"ultrasound-frequencies"}
