Question: 1 / 745

When is a V-shaped wave created and what are they commonly referred to as?

When the source is smaller than the wavelength, called spherical waves

When the source matches the wavelength, called spherical waves

A V-shaped wave is created when the source of the wave is larger than the wavelength. This phenomenon occurs because the wavefronts can be considered parallel and equal in distance as they spread out, leading to a focused beam that diverges into a distinct V shape. This type of wave is commonly referred to as a "plane wave."

The distinction lies in how the wave behaviors are defined based on the relationship between the source dimensions and the wavelength. When the source of the sound wave is comparable in size or larger than the wavelength, it generates well-defined wavefronts that resemble planes, creating significant acoustic directionality. Hence, the correct classification aligns with the characteristics of plane waves that arise from a sufficiently large source. Understanding this concept is critical in sonography as it affects how ultrasound waves propagate through different media.
