Ray Optics (Fundamental Concepts) Chapter 9 Class 12 #ncertphysics #Rayoptics #mirror #Raydiagarams

Physics By Jena sir (DREAMS ACADEMY, Chandigarh)
Learning Physics is simplified with strong Fundamental Concepts
In this topic we will discussthe following concepts
Ray Optics or Geometrical Optics In this optics, the light is considered as a ray which travels in a straight line. It states that for each and every object, there is an image.
Reflection Reflection is the phenomenon of changing the path of light without any change in the medium.
Reflection of Light The returning back of light in the same medium from which it has come after striking a surface is called reflection of light.
Laws of Reflection
Two laws of reflection are given as below:
(i) The angle of incidence i is equal to the angle of reflection r.
i.e. ∠i = ∠r.
(ii) The incident ray, reflected ray and normal to the reflecting surface at the point of incidence all lie in the same plane.
