difference between concave and convex mirror with example( answer in short)
Answers
Answer:
What is the difference between Concave and Convex mirror? Spherical mirrors whose inner side is reflecting are called concave mirrors. Spherical mirrors whose outer side is reflecting are called convex mirrors. It's focus and centre of curvature lies behind the mirror.
Difference Between Concave And Convex Mirror
Mirrors are smooth, polished or shining surfaces. They reflect the light beam and creates images. Thus, there are two kinds of mirrors, plane and spherical mirrors. Further, spherical mirrors divide into convex and concave mirrors. It is important to know the difference between concave and convex mirror to get a clear understanding. Basically, the reflecting surface of convex mirror bulges outside while concave mirror’s bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while enlarged images form in concave mirrors.
Definition of Concave Mirror
Concave mirrors are converging mirrors. The parallel incident rays fall on the mirror’s surface and the rays reflect and meet at a certain point known as the focal point. Concave mirror’s shape is similar to a spoon. When we place this mirror too close to an object, you get a magnified and virtual image. However, when there is an increase in the distance between the object and the mirror, the size of the image will reduce thereby creating a real image. Thus, the image which forms may be large or small, real or virtual.
Definition of Convex Mirror
Convex mirrors are diverging mirrors. In these, the incident ray which emerges from the same point reflects off and moves in a different direction. As a result, the light rays do not intersect on the mirror’s object side and create the virtual image of the real object. You can call it a kind of spherical mirror in which the reflective surface curves outwards. It will create a virtual image after it reflects from the mirror, the ray of lights will meet at an exact point. Moreover, the image which forms is erect, diminished and concerns the object.

Basis of Comparison Convex Mirror Concave Mirror
Meaning It’s a mirror that has a reflecting surface away from the centre of curvature A concave mirror is one that has a reflecting surface towards the curvature’s centre
Type Diverging mirror Converging mirror
Shape
Centre of Curvature It lies behind the mirror It lies in front of the mirror
Image Virtual image forms Real or virtual image forms
Projection Images do not project on the screen because they are virtual Images project on screen because they are real
Uses We use them as rearview mirrors in cars and bikes We use them as reflectors in projectors, searchlights, shaving mirrors and more
View These cover a wider area of view These give a magnified image of objects
