Scalloping a fretboard for a guitar involves removing material between the frets to create a concave shape. This can be done using a specialized tool called a fretboard scalloping file. Carefully and evenly file the wood between the frets to create the desired scalloped shape. Be sure to take your time and work slowly to avoid removing too much material.
The main differences between a baroque bow and a modern bow lie in their design and performance. Baroque bows are shorter, lighter, and have a convex shape, while modern bows are longer, heavier, and have a concave shape. Baroque bows are better suited for playing music from the Baroque period, offering a softer and more delicate sound, while modern bows are more versatile and provide greater power and control for a wider range of musical styles.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
The center of curvature in a concave mirror is important because it is the point where the mirror's surface is perfectly curved. Light rays that are parallel to the mirror's principal axis and strike the mirror will either converge or diverge at this point, depending on the mirror's shape. This point helps determine the focal length and image formation in concave mirrors.
Concave, because you can connect the corners from the outside.
Concave is a property of [irregular] polygons. A parallelogram cannot be concave.
