What type of asbestos fibers are characterized as wavy?

The correct response is that serpentine asbestos fibers are characterized as wavy. This type of asbestos, which includes chrysotile as the most common form, features long and curly fibers that can easily bend and twist. The wavy structure of these fibers allows them to be more flexible compared to other types of asbestos fibers.

In contrast, amphibole asbestos fibers tend to have a straight, needle-like appearance and do not possess the wavy structure seen in serpentine asbestos. Although chrysotile is indeed a form of serpentine asbestos, the answer specifically refers to the broader category of serpentine, which encompasses the distinct wavy characteristic. Fiberglass, while a fibrous material, is not classified as asbestos and does not share the same properties or health impacts associated with asbestos fibers.
