Instruction: Identify the type of mirror used in the following illustration whether plane, concave or convex mirror

Various positions of placing an object in front of the concave mirror gives us various positions of images.If an object is placed between the pole and focus of the concave mirror then image will be formed on the other side of the mirror. That image formed will be enlarged and virtual

Image formed will be virtual and of the same size as the object.

For convex mirror the image formed is always virtual and diminished

Hence as discussed concave mirror can form both real and virtually enlarged images and convex mirror forms only virtual diminished images and plane mirror always forms virtual images of the same size as objects.

So for A and B its concave mirror and for C it is convex and for D its plain mirror

Explanation:

they start with the same

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
