We take the velocity of microwave as 3*10^8 m/s and that of ultrasound wave is 330m/s.
Since, wavelength is same, so, velocity is directly proportional to frequency.
Therefore, ratio of frequency= ratio of velocity=velocity of microwave/ velocity of ultrasound wave=3*10^8/330=10^7:11
Please mark me the brainliest if you like my answer as its very urgent.
