A crater is typically concave, meaning it has a depressed or sunken appearance, with the center lower than the rim. This is due to the force of impact during the formation of the crater, which creates a bowl-shaped depression in the ground.
When light passes through a concave lens, it diverges or spreads out. This causes the light rays to bend away from each other. In contrast, when light goes through a convex lens, it converges or comes together at a focal point. This causes the light rays to bend towards each other.
A magnifying glass is convex.
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
Flashlights typically have a convex lens. A convex lens is thicker in the middle and thinner at the edges, which helps to converge the light rays and create a focused beam.

There are four types of concave (not cocave) hexagons:one reflex angle,two reflex angles, opposite one another,two reflex angles with one next-but-one to another,three reflex angles alternating.This site is not suitable for displaying images.
a polygon is convex
No. Copernicus crater is an impact crater.
A non convex is a concave and a convex is differently shaped
projector have concave or convex
In general, you cannot. All that you can say for a polygon with n sides is that the angles sum to (n-2)*pi radians - or (n-2)*180 degrees. This is true for cocave polygons as well as convex ones. For a concave polygon, if you wish to measure a reflex angle using a protractor, measure the outside angle and subtract that from 2*pi radians (360 degrees).
The cheese crater. The cheese crater is the cheeseiest crater in all of cheese land.
the union of two convex sets need not be a convex set.
