📘 A Quick Note About the Chapter
Reflection of light is the bouncing back of light into the same medium after it strikes a surface. A plane mirror forms a virtual, erect image of the same size as the object. The image appears as far behind the mirror as the object is in front of it.
The two laws of reflection state that the angle of incidence equals the angle of reflection, and the incident ray, reflected ray and normal at the point of incidence lie in the same plane.
Regular reflection occurs on smooth surfaces, while diffuse reflection occurs on rough surfaces. Both obey the laws of reflection. Lateral inversion is the apparent interchange of the left and right sides of an image.
💡 Remember Before You Begin
1. Angle of incidence = Angle of reflection.
2. Object distance = Image distance in a plane mirror.
3. A plane mirror forms a virtual, erect image of the same size.
4. If the mirror rotates by an angle, the reflected ray rotates through twice that angle when the incident ray remains fixed.
5. Diffuse reflection does not violate the laws of reflection.
