A round piece of plate glass is heated and slumped over a curved steel form then silvered on the convex side. Better ones were made by grinding and polishing a convex surface to one side of flat window glass then silvered on the curved side.
Because the Earth's surface is curved. You can only see a few miles from a standing position.
a shape of a lens is curved outwards and concave one are curved in wards
its because the lens of the microscope is convex. this means that it is curved a little bit, like the lenses of glasses. this causes the image to appear upside down. try looking into the curved part of a spoon from both sides. one side your reflection is normal, but on the other side your reflection is upside down, because of concave and convex. The side where you see your reflection normal is concave, and the side where it is backwards is convex. hope i helped!
The reason you only see one side of the moon is because you only see side of the moon is facing towards the Earth which means the back of the moon is nonvisible.
A circle or an oval (ellipse) This depends on what one calls a "side". Usually a side needs to be straight, as in the case of polygons.
A semicircle is one shape fitting this description.
circle
A lens is a piece of glass or other hard clear material molded with either one side flat and the other curved, or both sides curved. The curving side/s are to refract or bend light.
There is one curved side and two curved edges (the rims along the top and bottom).
a semi circle.. (:
A convex lens has one flat side and one curved side --> |) A biconvex lens has both sides curved --> ()
If you are referring to a shape, then a semi-circle would be the most likely shape that contains one straight side and one curved. Take a look at a protractor, it's a semi-circle.
A two-dimensional shape with one curved side and four straight sides can be created, but there is not specific name for such a shape.
A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
a sphere has no bases and it only has one curved surface
Irregular shape is the term given to an object which has 1 flat side, 1 curved side, no corners but has curved edges.
