Final answer:
Sound waves are reflected in the medical field for detecting diseases, monitoring fetal development, destroying cancer cells, locating damaged parts, and breaking down kidney stones, using ultrasound technology.
Step-by-step explanation:
In which applications are sound waves reflected? Sound waves are reflected in several important applications, particularly in the field of medicine. For instance, detecting diseases, monitoring fetal development, and breaking down kidney stones are some of the key applications. Ultrasound imaging utilizes sound waves to construct images of internal body structures, such as muscles and soft tissues, which is especially useful during pregnancy. Additionally, ultrasound can aid in locating damaged parts of the body by visualizing conditions inside, without being invasive or harmful.
Moreover, focused ultrasound is used in therapeutic applications such as destroying cancer cells through localized heating and in physical therapy. While not specifically mentioned in the resources provided, sound waves also have applications in engineering, like nondestructive testing, and they are also used for cleaning, but not specifically for lenses. Therefore, the applications where sound waves are reflected and are relevant to the provided information include detecting diseases, destroying cancer cells, locating damaged parts, breaking down kidney stones, and monitoring fetal development.
