    Study Notes

    Mirrors

    • Mirrors reflect light, producing images.
    • Light reflecting off an object creates an image in a mirror.
    • Mirrors come in various types, including plane and curved.

    Types of Mirrors

    • Plane mirror: A flat mirror producing a virtual image.
    • Curved mirror: A mirror with a curved reflecting surface.

    Reflection of Light

    • Reflection is the bouncing back of light when it hits a surface.
    • The angle of incidence equals the angle of reflection.
    • A normal line is perpendicular to the mirror's surface.

    Additional Terms

    • Incident ray: The incoming beam of light.
    • Reflected ray: The outgoing beam of light.
    • Normal: A line perpendicular to the reflecting surface.
    • Angle of incidence: The angle between the incident ray and the normal.
    • Angle of reflection: The angle between the reflected ray and the normal.

    Activity: Investigating Mirrors

    • Students will be provided with mirrors to observe characteristics of mirrors.
    • Types of mirrors used: plane, concave, and convex
    • Students will record their observations.

    Laws of Reflection

    • The angle of incidence is equal to the angle of reflection.
    • The incident ray, the reflected ray, and the normal lie in the same plane.

    Image Formation by Plane Mirrors

    • Location: The image is located behind the mirror.
    • Orientation: The image is upright (same orientation as the object).
    • Size: The image is the same size as the object.
    • Type: The image is virtual (cannot be projected onto a screen).

    Image Formed by Convex Mirrors

    • Location: The image is always behind the mirror.
    • Orientation: The image is always upright.
    • Size: The image is always reduced.
    • Type: The image is always virtual.

    Image Formed by Concave Mirrors

    • Location: The image's location depends on the object's distance from the mirror.
    • Orientation: The image can be either upright or inverted, depending on the object's location.
    • Size: The image can be either smaller, larger, or the same size as the object, depending on the object's location.
    • Type: The image can be either real or virtual, depending on the object's location.

    Important Points (Curved Mirrors)

    • Center of curvature (C): The center of the sphere of which a curved mirror is a part.
    • Vertex (V): The center of the mirror.
    • Focal Point (F): The point between the center of curvature and vertex.
    • Principal axis (P): An imaginary line passing through the vertex and perpendicular to the mirror.

    Rules for Drawing a Ray Diagram in a Convex Mirror

    • Draw the plane mirror and the normal line
    • Place the object along the normal line
    • Draw a line from the tip of the object going to the intersection of the mirror and normal line.
    • Measure the incidence angle, then draw the reflected ray using the same degree for the reflected angle.
