A star shape can be classified as convex or concave depending on its specific design. A convex star, like a typical five-pointed star, has all its interior angles less than 180 degrees, meaning that any line segment drawn between two points inside the star will lie entirely within it. In contrast, a concave star has at least one interior angle greater than 180 degrees, resulting in indentations that create "inward" points. Thus, whether a star is convex or concave depends on its geometric properties.

Do microscopes use concave or convex lenses?
Microscopes primarily use convex lenses. Convex lenses converge light rays to create a magnified image. There are also compound microscopes that incorporate both convex and concave lenses to enhance the quality of the image.

What is important in concave and convex mirror?
In concave mirrors, the focal point, focal length, and magnification are important. Concave mirrors can form real or virtual images depending on the object's position relative to the mirror. In convex mirrors, the field of view and image size are important. Convex mirrors always produce virtual images that are smaller and upright compared to the object.
