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. wat is the speed of the waves from the second source in the original medium? wat is the is trhe speed of the reflected waves from the first source in the orignal medium? Will the angle of the refraction of the waves from the second source be greater than, less than, or equal to 35 degree as they enter the different medium? wat is the wavelength of the waves from the second source in the orignal medium? wat is the wavelength of the waves from the second source in the different medium? ALSO i wanna know wat the constant k's units are and wat does this constant tell me?
