Physics/ Experiment/ Doppler Effect?

Question

Hi, I have just completed an experiment that demonstrates the Doppler Effect, by recording the sound of a car horn + analysing frequency. However I have a number of general questions;

- Why was my method appropiate for me? (eg. was cost effective)

- Why did I chose to do it individually

- How is the Doppler Effect applied in ultrasonics to obtain flow characteristics of blood blow through the heart

- How could of my method included reflective sound??????

- How could the accuracy and reliability be imporved in my method, ESPECIALLY ASSUMING FEWER LIMITAIONS TO THE RANGE OF AVAILABLE TECHNOLOGIES????

Please if you can, answer any of the questions above. Especially the reflective sound one, wtf???

Thanks billions

Answer 1

"Why did I choose to do it individually?" How the f*cking h**l are we supposed to know? Do your own d**n homework.

Answer 2

since you don't tell us what method you used, it is hard to answer most of these questions; for the blood flow, look up on line references to "Doppler Echocardiogram"
