Homework Statement
two vibrating sources emit waves in the same elastic medium. the first source has a frequency of 25 hz, while the frequency of the second source is 75hz. waves from the first source have a wavelength of 6.9 m. they reflect from a barrier back into the original medium, with an angle of relfection of 25 degrees. waves from the second source refreact into a different medium with an angle of incidence of 35 degrees. the speed of the refracted waves is observed to be 96 m/s.
ok so i need help with the set up and the digram at this problem. i only learned reflection as an indivudual question and retraction as an individual question.
my attemp was to draw the t lines, have one bouncing off from one and on the other flip side have only one bounc off..can anyone help and explain how to do this? greatly appreciated..im in grade 11 phyics corrospondants during the summer...and i need someone to help...
