Two different transducers create pulses. One transducer is labled 5 MHz and the other, 3 MHz. The 3 MHz transducer creates a more accurate image with relation to axial resolution. Explain
The 3 MHz pulse must be shorter than the 5 MHz pulse. SInce 3 MHz has a longer wavelength than 5 MHz, the only way that the 3 MHz pulse is shorter is if the 3 MHz transducer rings less. Thus, the 3 MHz pulse is made of fewer cycles.
