Please solve the question in a step by step process. 1. What is the wavelength of a 3.3 MHz sound in soft tissue? (answer is not 5.082x10^-3) answer must be represented in mm What is the frequency of an unknown wavelength traveling in soft tissue? 3.25MHz 2.The pulse duration of a pulsed wave is 1.02 s, and the pulse repetition period is 0.15 ms. What is the duty factor? (answer is not 0.68 or 68) The sonographer increased the depth of view. The pulse duration then{ did not change} , and the duty factor {decreased} .
