plano concave
A plano-concave lens is a type of lens that has one flat surface (plano) and one concave surface that curves inward. It causes light rays to diverge after passing through it, making it useful for applications that require spreading out light, such as reducing the intensity of a beam.

A concave mirror can create a real image.
A concave mirror is usually used on the back of a spoon. This type of mirror curves inward, allowing it to reflect light in a way that magnifies the image. It is commonly found in things like makeup mirrors or dentist's tools.
No, a spherical mirror is a general term that refers to a mirror with a curved surface, while a concave mirror specifically has a reflective surface that curves inward, like the inside of a sphere. Concave mirrors can be one type of spherical mirror, along with convex mirrors.

A reflecting telescope.
A concave mirror can be used to obtain a real image of an object. This type of mirror curves inward, causing light rays to converge at a point, creating a real and inverted image. The image produced by a concave mirror can be projected onto a screen.
