| The animation deals with the following aspects of spherical mirrors : 1. Firstly why are they called spherical mirrors , where is the sphere 2.What is the nature of the image formed by spherical mirrors? 3. Can a real image be formed in a convex mirror? This animated physics (optics) software gives in-depth information about spherical mirrors and is very useful for students and teachers for e-learning purpose.

Properties
of Spherical Mirrors:
How are spherical mirror made from
a sphere ?
What is the difference between convex
and concave mirror ?
What are center of curvature, radius
of curvature, pole, principal
axis, focus, focal length and aperture
How do we calculate objective and
image distance, magnification,
sign convention, focal length etc. Formula and tables are
provided (In explanatory notes)

Spherical mirrors - convex and concave
mirrors- are a part of a sphere. Focus, pole and Radius
and center of curvature are shown in the diagram
|
A concave mirror is made by silvering
the surface on one side, rays parallel to the axis meet
on the focus
|
 |
|
|
Convex mirror : the rays diverge out
and apparently meet at focus
|

on convex mirror

A spherical mirror is made by silvering
the piece of a glass, which is the part of a hollow sphere.
A concave mirror is made by silvering the outer or bulging
surface of a part of a sphere and the reflection takes place
from the hollow inner surface.
A convex mirror is made by silvering the inner surface such
that the reflection takes place from the outer/bulging surface.
1. What is the nature of the image formed by spherical mirrors?
2. Where is the image formed if object is at a large distance
from the mirror?
3. Can a real image be formed in a convex mirror?
4. Are the images formed in spherical mirrors of the same
size as object?

| Ans: |
Rear view mirrors used in vehicles is the most common application of mirror; they are also used in malls, banks and shops for security reasons, they are also used in laser ranging to the moon, parabolic mirrors are used in solar energy and for signaling. They are also used in projection system for planetarium instead of fish eye lens to distribute light in a wide solid angle. |

| Ans: |
Thanks for your query, we have a range of animation targeted for high school or college level students, we are emailing the list to you, to view them online a subscription is needed or buy and download to your computer them otherwise order them on a CD. We have got free samples of each in “preview” section, other wise you can view a half-hour animation on “Journey into atom” from the downloads section. We can also e-mail it to you. |

| Ans: |
We cannot draw a diagram as this answer only supports text. Please refer to the concave mirror animation. For your reference beyond 'C' image will be inverted, between F and mirror it will be upright |
