Study Notes
Light and Wave Phenomena
- Light is a form of energy that travels as electromagnetic waves.
- Exhibits five wave phenomena: reflection, refraction, diffraction, interference, and polarization.
Reflection of Light
- Reflection involves light bouncing off surfaces.
- First Law: The incident ray, normal, and the reflected ray lie in the same plane.
- Second Law: The angle of incidence (i) equals the angle of reflection (r).
Types of Spherical Mirrors
- Two types: concave mirrors (caved in) and convex mirrors (bulged out).
- Centre of curvature (C) is the point representing the spherical surface, while focal point (F) is halfway between C and the pole (P).
- The principal axis runs through the pole, focus, and centre of curvature.
- Focal length is the distance from the pole to the focus.
Behavior of Light in Concave Mirrors
- Parallel incident rays reflect through the focus (F).
- Rays passing through focus are reflected parallel to the principal axis.
- Rays passing through the centre of curvature reflect back along their own path.
Image Formation by Concave Mirrors
- Object beyond C: Image is between C and F, real, inverted, and diminished.
- Object at C: Image is at C, real, inverted, and same size as the object.
- Object between C and F: Image is between C and F, real, inverted, and diminished.
- Object at F: Image appears at infinity.
- Object inside F: Image is behind the mirror, virtual, upright, and magnified.
Behavior of Light in Convex Mirrors
- Parallel incident rays reflect and appear to come from the focal point.
- Rays aimed at the centre of curvature reflect back along their original path.
- Image formed by convex mirrors is always behind the mirror, virtual, upright, and diminished.
Focal Length of Concave Mirrors
- Focal length (f) can be calculated using a specific formula.
- Sign convention: In front of the mirror is positive, meaning:
- f > 0 for concave mirrors
- v > 0 for real images
