WebUltrasound is useful because it has a short wavelength so it can be focussed into a beam. Uses of ultrasound - Higher. Ultrasound scans are used to form images of things inside … WebFor an EM wave, intensity is defined as E2/Z, where E is the rms amplitude of the wave's E-field, and Z is the intrinsic impedance of the medium. Its dimensions are power per unit area. The reflection and transmission coefficients we measured are in terms of amplitude; and therefore, are proportional to the square root of those based on intensity. electric bicycle built for two
