Advance Course AIIMS-SYLLABUS Physics syllabus Spherical Mirrors

Spherical Mirrors

Spherical mirrors are curved mirrors that have a spherical shape. They are classified into two types: concave mirrors and convex mirrors.

1. Concave Mirrors: A concave mirror curves inward, causing light rays to converge. The center of the curvature (C) is located behind the mirror, and the focal point (F) is half the radius of curvature (R) in front of the mirror. The principal axis is the line passing through the center of curvature and the vertex of the mirror.Key features:
   • Concave mirrors can form both real and virtual images depending on the position of the object.
   • When the object is placed beyond the focal point (F), a real and inverted image is formed between the focal point and the mirror.
   • When the object is placed between the focal point and the mirror, a virtual and magnified image is formed on the same side as the object.
   • The magnification of the image can be determined using the magnification formula (m = h’/h), where h’ is the height of the image and h is the height of the object.
2. Convex Mirrors: A convex mirror curves outward, causing light rays to diverge. The center of curvature (C) is still behind the mirror, but the focal point (F) is located behind the mirror as well. The principal axis remains the line passing through the center of curvature and the vertex of the mirror.Key features:
   • Convex mirrors always form virtual images.
   • The images formed by convex mirrors are always diminished, upright, and located between the mirror and the focal point (F).
   • The image distance is negative in convex mirrors, indicating that the image is virtual and formed on the same side as the object.

Understanding the properties, ray diagrams, mirror formula, and mirror equation associated with concave and convex mirrors is crucial to analyze the formation of images and their characteristics.

The physics syllabus for spherical mirrors in the AIIMS (All India Institute of Medical Sciences) entrance exam typically covers the following topics:

1. Reflection of Light: Laws of reflection, plane mirrors, and spherical mirrors.
2. Spherical Mirrors: Concave and convex mirrors, their characteristics, and properties.
3. Ray Diagrams: Drawing ray diagrams for concave and convex mirrors to determine the position, nature, and magnification of the image formed by an object.
4. Mirror Formula: Derivation and application of the mirror formula (1/f = 1/v – 1/u), where f is the focal length, v is the image distance, and u is the object distance.
5. Mirror Equation: Understanding and using the mirror equation (h/v + h/u = 1), where h is the height of the object and h’ is the height of the image.
6. Magnification: Calculation of magnification (m = h’/h) and understanding its significance in determining the size and orientation of the image formed by a spherical mirror.
7. Mirror Combinations: Analysis of mirror combinations, such as multiple mirrors placed in various orientations, to determine the final image formed.

It is essential to have a strong understanding of the concepts mentioned above, as well as the ability to solve numerical problems related to spherical mirrors.
