##### 1 : Reflection of Light

- Laws of Reflection:
- Angle of Incidence ((i)) = Angle of Reflection ((r)).
- Incident ray, reflected ray, and the normal to the surface lie in the same plane.

- Plane Mirrors:
- Characteristics and properties of images formed by plane mirrors.
- Virtual, erect, and same-size images.

##### 2 : Spherical Mirrors

- Types of Spherical Mirrors: Concave and Convex.
- Mirror Formula: $$(\frac{1}{f} = \frac{1}{v} + \frac{1}{u}),$$ where (f) is the focal length, (v) is the image distance, and (u) is the object distance.
- Sign Conventions for Mirror Formula:
- Distances and focal lengths (positive and negative signs).

- Magnification $$((M)): (M = -\frac{v}{u}),$$ indicating the nature and size of the image.
- Ray Diagrams:
- Drawing ray diagrams for various mirror-object configurations.
- Determining the position and nature of the image.

- Mirror Equation Shortcut: Quick estimation of image position when the object is at infinity.

##### 3 : Formation of Images

- Real and Virtual Images.
- Characteristics of Images:
- Real: Inverted and can be formed on a screen.
- Virtual: Upright and cannot be formed on a screen.

- Image Formation Rules for Concave Mirrors:
- Object beyond the center of curvature ((C)), between (C) and focus ((F)), at (F), and between (F) and the mirror.

- Image Formation Rules for Convex Mirrors:
- Always virtual, upright, and diminished.

- Concept of Principal Focus ((F)) and Focal Length ((f)).
- Concept of Center of Curvature ((C)).
- Real and Virtual Focus.
- Characteristics of Different Mirror-Object Configurations.
- Magnification and Inversion.
