If the speed of sound in tissue is 1540 m/s and the frequency is 1 MHz, the wavelength is approximately

Explanation:
Wavelength is found by dividing the speed of sound by the frequency. With a speed of 1540 m/s and a frequency of 1,000,000 Hz (1 MHz), the wavelength is 1540 / 1,000,000 = 0.00154 meters, which converts to 1.54 millimeters. This matches the option given as 1.54 mm. The other values arise from unit or decimal misplacements: 0.154 mm would require a higher frequency, around 10 MHz; 15.4 mm would correspond to a much lower frequency (about 100 kHz) for the same speed; and 0.0154 cm equals 0.154 mm, not 1.54 mm.
