Click For Summary
Placing an aluminum plate between an ultrasound device and its target will significantly affect the ultrasound's ability to reach the target due to reflection and absorption. The aluminum will reflect a portion of the ultrasound energy, while the remaining energy may be absorbed by the plate, depending on the frequency and intensity of the ultrasound. The surrounding air also influences the transmission, as it has a different acoustic impedance compared to aluminum. The exact amount of energy reaching the target can be calculated by considering these factors, including the specific parameters of the ultrasound. Understanding these interactions is crucial for applications utilizing focused ultrasound technology.

TL;DR
Ways of blocking ultrasound
Hello. I have a question in relation to blocking ultrasound. Suppose we have a device which emits ultrasound. Lets suppose that is is focused ultrasound, and it emits it towards a target at a displaced location. The question is, if you place an aluminum plate between the target location and the device, supposing further that the surrounding medium of the aluminum plate is air, what will happen with respect to the ultrasounds ability to reach the target point?

Suppose you characterize the ultrasound in accordance with various parameters such as frequency, intensity, energy and potentially other parameters. How much of the original ultrasound energy would reach the target point considering the aluminum plate that sits between the device and the target point? Include in your answer consideration of reflection as well as absorption and any other mechanisms for the interaction with the ultrasound.

That doesn't sound like a question you came up with. You should post it in the homework forum with an attempt at a solution.

Thread 'Reference frames, center of rotation, etc'

Topic about reference frames, center of rotation, postion of origin etc Comoving ref. frame is frame that is attached to moving object, does that mean, in that frame translation and rotation of object is zero, because origin and axes(x,y,z) are fixed to object? Is it same if you place origin of frame at object center of mass or at object tail? What type of comoving frame exist? What is lab frame? If we talk about center of rotation do we always need to specified from what frame we observe?
