BUT this is the total distance travelled by the sound - so the depth is half of this . //-->. Intensities this great can damage individual cells, variously causing their protoplasm to stream inside them, altering their permeability, or rupturing their walls through cavitation. By definition, ultrasound is sound having a frequency greater than _____ cycles per second, that is, sound above the audible range. The scope of the questions in the book is broad, including areas such as applied ultrasound physics, haemodynamics, valvular problems, ischaemic heart disease, congenital heart diseases, intraoperative or surgical echocardiography, pericardial diseases and cardiac masses. All the students would study the same way. Attenuation is the reduction in sound wave intensity and amplitude when traveling through a medium and is the reason why echoes from deeper structures are weaker than echoes from superficial areas. Physics of Echocardiography. Note: Remember that the distance travelled by the sound is doubled for echo. This type of question is considered advanced because it requires a higher GCSE PHYSICS WAVES & SOUNDS High Demand Questions QUESTIONSHEET 3 (a) A man claps his hands on a hilltop.

Now he hears an echo after 5.25s. 1. State one property of waves used for echo depth sounding. But whereas a light beam 'spreads out' very little, sound 'spreads out' quite a lot - and we therefore do not think of it as being 'directed' in a path from a speaker, we consider it to spread out everywhere!
