-- A concave mirror gathers the light and bunches it up all in one place, called
the "focus" of the mirror. There's a "real image" at that place, and you can
capture it with a piece of ground glass, tissue, photo-film, or light-sensitive device
at that place.
-- A plane mirror doesn't gather anything. It just kind of sends the light back
toward where it came from. It doesn't form any real image, and there's nothing
to capture.
concave
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
You could make a Newtonian reflecting telescope with those parts.
A concave mirror is curved like the inside of a bowl instead of being flat.
If our image is real and inverted and smaller than the object ,then it is a concave mirror; if the image is virtual and erect and larger than the object,then it is a convex mirror; if the image is of the same size as of the object,it is a plane mirror. that is how we can distinguish or identify which of the given mirrors are what. BUT if the angle is very small you cannot tell Plane is flat, convex it curves outwards and concave it curves inwards.
The telescope is cylindrical. Its primary mirror is concave.
The diameter of the concave mirror.

Concave means bulging inward - reflecting telescopes use this sort of mirror. The first telescope designed to use one was invented by Isaac Newton and they are therefore called "Newtonian" telescopes.
a. concave mirror b. a convex lens c. a plane mirror or d. all the above.
