Explanation:
Case (i): If the image is upright, of same size and it does not change in size by moving the mirror towards or away from the face, the mirror is plane. (ii) If the image is upright and magnified, and increases in size on moving the mirror away, the mirror is concave...
Answer:
what is a mirror?
When you look at yourself in a mirror, you see a nice, clear image. It's quite different to your reflection on a shiny car. And most surfaces you see in everyday life aren't reflective at all. You certainly don't see your reflection in the kitchen table. That's because, while the table might feel smooth, it actually isn't. If you could look at most surfaces under a microscope, you would see a landscape of peaks and valleys.
A mirror is a surface that is smooth enough that it produces specular reflection - clear reflections - so you can see an image. But mirrors can be made into different shapes for different purposes. Two of those shapes are planes and spheres.
PLANE MIRRORS Vs SPHERICAL MIRRORS:-
A plane is a flat surface. So a plane mirror is just a smooth, mirrored surface that is completely flat. This stops the image you see from being distorted. The opposite of this might be a fun-house mirror, where the various bends and shapes can make the image look ridiculous.
A sphere is the 3D version of a perfect circle - it's a shape with a consistent curve all the way around and a constant radius. So a spherical mirror is a mirror that has a consistent curve and a constant radius of curvature - a sphere-shaped mirror.
Spherical mirrors can be convex or concave, depending on which side you put the mirrored surface on. A convex mirror is a spherical mirror where the mirrored surface is on the outside of the spherical curve. And a concave mirror is a spherical mirror where the mirrored surface is on the inside of the spherical curve.
Plane mirrors produce virtual, upright images that are the same size as the object. Virtual, by the way, just means the image is formed behind the mirror instead of in front of it.
Concave mirrors produce different kinds of images, depending on whether the object is placed further away from the mirror than the focal point or inside the focal point. And convex mirrors always produce images that are upright, virtual and smaller than the object.
