Magnifying glasses use convex lenses
The outer curved part is coated with mercury as the inner would reflect light in case of concave mirror. Whereas the inner is coated as to make the outer to act as reflector in case of convex mirror. Concave mirror can give both real and virtual images for a real object depending on the location of object. But convex on the other hand can give only virtual image with a real object irrespective of the position of the object. Next, concave mirror can be used as shaving mirror. Also used to converge the parallel beam of light. Convex mirror is best used as rear view mirror in case of vehicles.
A magnifying lens is convex i.e. it bulges outwards. A concave lens would make objects appear smaller.
Yes convex and concave mirrors are also known as spherical mirrors. If mercury coating is made on the convex side of the spherical then mirror is known as concave mirror. If mercury coating is made on the concave side the convex portion would reflect the light fallen so it is named as convex mirror. Actual just a small part of the sphere is taken out and this would act as the spherical mirror.
Concave mirror would have the surface curved out get coated with mercury hence curved in surface would reflect the rays fallen on. But convex mirror would have the surface curved in get coated with mercury hence curved out surface would reflect the rays fallen on. Concave mirror would have both converging and diverging ability. When light coming from an object placed at a distance higher than its focal length right from the pole of the mirror, converging takes place. But the object lies in between pole and the focus diverging action. But in convex mirror irrespective of the placement of the object only diverging phenomenon. Concave mirror used as shaving mirror and dentists too use them Convex mirror is used as rear view mirror in case of vehicles near by the driver.
It would be concave lens. This is because it diverges the light before it enters the eye.
You would use a convex lens.
a concave lense
You would use a convex lens.

i guess it doesnt really matter. my magnifying glass is a convex lens so yaaaa. well that's all i got cuz this website don't even no what a concave or convex lens is.
If it were a perfect heptagon then it would be convex. If it had any indentations then it would be concave.
A normal 2-D quadrilateral would be neither convex or concave. There are three-dimensional quadrilaterals, such as prisms, but it would depend on the shape.

A concave quadrilateral would be a non-convex quadrilateral. * * * * * Also known as delta or arrowhead or chevron.
