Question

what are mirror and type of mirrors? In detail

Answer 1

mirrors come in two basic flavors: convex and concave. A convex mirror, which bulges outward, reflects at a wider angle near its edges than at its center, creating a slightly distorted image that's smaller than actual size. Convex mirrors have many uses. The smaller size of the images means that you can see more with these surfaces, hence their use in safety mirrors.

Answer 2

In plane mirror , the image formed is always behind the mirror erect , virtual of same size of the object at the same distance from the mirror the image is laterally inverted if the mirror is rotated by 0 degree angle the reflected ray is rotated by angle 20 degree the length to the mirror required to see one's full image is just half of own length. if there are two parallel mirror parallel infinite image are formed. if there are two perpendicular mirror, three image are formed. A thick mirror forms a number of images out of which second image is brightest.
Spherical mirror (concave or convex): the principal focus is defined as the convergence point for rays parallel to the axis of mirror. it is a located Halfway between the mirror and the centre of curvature.image formed by concave mirror :Image at focus, inverted, real and , diminished
image formed by convex mirror : image always behind the mirror , erect virtual and diminished
formula 1/v+1/u=1/f=2/r ( for both mirror)
u = distance of the object from pole
v =distance of the images from pole
f= focal length
linear magnification
m =length of images/length of object = -v/u
m is positive for virtual image and negative for real image
