Occurs when two waves in phase with each other create a new wave with amplitude greater than the original two waves

Occurs when two waves in phase with each other create a new wave with amplitude greater than the original two waves

• A. Contructive Interface
• B. Convex Array
• C. Currie Point
• D. Damping

Answer: (A)

When two waves are in phase, their peaks line up with peaks and their troughs line up with troughs, so their amplitudes add together. The result is a wave with greater amplitude than either of the original waves—this is constructive interference. In ultrasound, this means regions where waves reinforce each other become brighter or have higher intensity because the energy combines in that spot. If the waves were out of phase, they could partially cancel each other out, leading to lower amplitude—destructive interference. The other terms listed aren’t about how wave amplitudes combine: a convex array refers to the shape of a transducer, the Curie point is a magnetic property temperature, and damping describes the loss of energy and decrease in amplitude as a wave travels.
