Ultrasound waves propagate from medium A (ZA = 1.5 MRayl) to medium B (ZB = 2 MRayl). What would be the intensity transmissivity at the interface? The incident angle is zero degrees. A-0.1 B-0.02 C-0.98 D-0.9
Added by Tamara K.
Step 1
5 MRayl and ZB = 2 MRayl, we can plug in the values: \[ R = \left(\frac{2 - 1.5}{2 + 1.5}\right)^2 \] \[ R = \left(\frac{0.5}{3.5}\right)^2 \] \[ R = \left(\frac{1}{7}\right)^2 \] \[ R = \frac{1}{49} \] \[ R = 0.02 \] Show more…

The intensity of a polarized electromagnetic wave is $10 \mathrm{W} / \mathrm{m}^{2} .$ What will be the intensity after passing through a polarizing filter whose axis makes the following angles with the plane of polarization? (a) $\theta=0^{\circ}$ (b) $\theta=30^{\circ}$ (c) $\theta=45^{\circ}$ (d) $\theta=60^{\circ},$ (e) $\theta=90^{\circ}$
A 10-kHz electromagnetic wave in air with parallel polarization is incident obliquely on an ocean surface at a near-grazing angle ̧̧́i = 88°. Using εr = 81, μr = 1, and σ = 4 (S/m) for seawater, find (a) the angle of refraction θt, (b) the transmission coefficient τ∥, and (c) the distance below the ocean surface where the field intensity has been diminished by 30 dB.
