Light – Reflection and Refraction – Notes
Reflection
Based on the nature of the reflecting surface, reflection can be regular and irregular.
Images can be real images that can be caught on a screen, or virtual images that cannot be caught on a screen. Images formed in a plane mirror are virtual.
According to the laws of reflection:
- The angle of incidence (i) equals the angle of reflection (r).
- The incident ray, the reflected ray and the normal all lie in the same plane.
The image formed in a plane mirror is erected, laterally inverted, the same size as the object, and the distance of the image from the mirror is equal to the distance of the object from the mirror.
