In medical diagnostics, clinicians utilize both ultrasound scanners (which propagate high-frequency acoustic waves through soft tissue) and Magnetic Resonance Imaging (MRI) scanners (which utilize radiofrequency electromagnetic waves).
Which wave phenomenon can be exhibited by the radiofrequency waves of the MRI scanner, but cannot be exhibited by the acoustic waves of the ultrasound scanner in soft tissue?
Refraction (bending of the wave path) when passing obliquely across a boundary between different tissue media.
Plane-polarisation, restricting the direction of wave oscillations to a single plane.
Constructive and destructive interference when multiple coherent wave paths overlap.
Reflection at a boundary separating tissues with different physical properties.
