real and virtual images
when an object is placed atinfinity, the rays coming from it are parallel to each other. These rays after reflection form an image at the focus.
The image is
when object is placed beyond cthen the image is
when object is placed at centre of curvature then the image is
when object is between C and F then the image is
when object is at focus then the image is
when object is between pole and focus then the image is
Virtual and real images
Two types of curved mirrors are: concave and convex.
there are three kinds of mirror 1) concave 2) convex 3) plane

real and virtual images
A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point.They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror.These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror.
A concave mirror can show both vitual and real images, a plane mirror can show virtual and so can a convex mirror. 0.0
Real images
Plane Mirror - are standard, flat mirrors, produce images of the same size and distance as the objects they reflect Concave Mirror - Used to focus light, they reflect it inward toward one focal point. Concave mirrors show different types of images, depending on the distance between the mirror and the object reflected. Concave mirrors are used quite frequently in day-to-day life
