What is the wavelength in soft tissue at 3 MHz if the speed is approximately 1540 m/s?

Explanation:
Wavelength is found by dividing the wave speed by its frequency. In soft tissue, the speed is about 1540 m/s, and a frequency of 3 MHz is 3,000,000 Hz. So λ = 1540 / 3,000,000 ≈ 5.13 × 10^-4 m, which is 0.513 mm. This matches the intuition that higher frequency yields a shorter wavelength, and it aligns with typical tissue values (about half a millimeter at 3 MHz).
