The speed of ultrasound in fat is 1,450 m/s, and in muscle it is 1,549 m/s. By what percentages do the frequency and wavelength of ultrasound change when passing from fat into muscle?
| percentage change in frequency | % |
| percentage change in wavelength |
Solution
lambda = c / f
The percent change in lambda is the same as the percent change in speed
= (1549 - 1450) / 1450
= 6.83 %
