An ultrаsоund beаm with а frequency оf 5 MHz passes thrоugh three different tissues with the following characteristics: Tissue A: 2 cm thick with attenuation coefficient 0.5 dB/cm @ 5MHz Tissue B: 3 cm thick with attenuation coefficient 0.7 dB/cm @ 5MHz Tissue C: 1 cm thick with attenuation coefficient 1.2 dB/cm @ 5MHz If the initial intensity of the ultrasound beam is 100 mW/cm², what is the approximate intensity after passing through all three tissues? The reflection at each interface is not considered here.
