What are spherical mirrors ?
Asked by Manjusha Madkaiker | 27th Jun, 2014, 09:06: PM
A reflecting surface which is a part of a hollow sphere of a glass is called a spherical mirror. A spherical mirror works on the principle of reflection of light.
Spherical mirrors are of two types: (1) Concave mirror (2) Convex mirror.
- A concave mirror is that spherical mirror in which the reflection of light takes place at the concave surface (or bent-in surface).
- It converges the light rays incident on it after reflection.
- It forms real as well as virtual image.
- The image can be magnified, diminished or of the same size as the object depending on the position of the object.
- A convex mirror is that spherical mirror in which the reflection of light takes place at the convex surface (or bulging-out surface).
- It diverges the light rays incident on it after reflection.
- It always forms a virtual image.
- The image formed is always diminished for all the positions of the object.

- The relation between focal length and radius of curvature is given by
- what is the convergence of light and where it is used
- The image of an object formed by a lens is of magnification -1. If the distance between the object and it's image
- In physics,what kind of image will be form when concave and convex mirror and in lens are kept together
- Is there any ratio for size of object in Convex mirror and real size of object ?
- Which mirror is used as a torch reflector?
- Source of light of kept at focus of mirror in headlighte of vehicles give reason
- A Ray of light passing through the centre of curvature of a concave mirror is incident on its reflecting surface . What is the angle of incidence and angle of reflection of this ray.
- What is the general value of magnification in lens and mirror
- An object is placed in front of a concave mirror of focal length 30 cm. The virtual image of the object is obtained at a distance 20 cm from the mirror. Calculate the position of the object. Please explain briefly step by step
