Diferance betwin concave mirror and convex …

Concave Mirror:
(i) A concave mirror is a spherical mirror in which the reflecting surface and the center of curvature fall on the same side of the mirror. In other words, if the mirror coating lies outside of the spherical surface, then it is known as a concave mirror.
(ii) Image can be projected on a screen.
(iii) The images formed by the concave mirrors are magnified in nature.               
(iv) The object in the image formed by the concave mirror look bigger than the original size of the object.
(v) Concave mirrors form real and inverted images except when the object is between pole and focus.                

Convex Mirror

(i) A convex mirror is a spherical mirror in which the reflecting surface and the center of curvature lie on the opposite sides of the mirror. In other words, if the mirror coating lies in the inside of the spherical surface, then it is known as a convex mirror.
(ii) Image cannot be projected on a screen.
(iii) The images formed by the convex mirrors are diminished in nature.
(iv) The object in the image formed by the convex mirror look smaller than the original size of the object.
(v) Convex mirrors form virtual and erect images irrespecive of the position of the object.
