Ray Diagram of Convex Mirror | Ray Directed Towards Principal Focus | With Angles Marked | Class 10 Physics
📖 YouTube Description:
In this video, we draw a labelled ray diagram of a convex mirror to show the path of the reflected ray when the incident ray is directed towards the principal focus (F).
👉 You will learn:
How to draw a convex mirror ray diagram step by step
What happens when a ray is directed towards the principal focus
Why the reflected ray becomes parallel to the principal axis
How to mark the angle of incidence (∠i) and angle of reflection (∠r)
Application of mirror formula and sign convention
This topic is very important for Class 10 CBSE Board Exams, foundation classes, and competitive exams like NEET & JEE (basic ray optics concept).
✏️ Ray Diagram Explanation
🔎 Concept:
In a convex mirror, the principal focus (F) lies behind the mirror.
When an incident ray is directed towards the principal focus,
After reflection, the ray becomes parallel to the principal axis.
📌 Important Points to Mark in Diagram:
Pole (P)
Principal Axis
Principal Focus (F) – behind the mirror
Centre of Curvature (C) – behind the mirror
Incident Ray
Reflected Ray (parallel to principal axis)
Normal at point of incidence
Angle of Incidence (∠i)
Angle of Reflection (∠r)
⚖️ Law Used:
According to the Law of Reflection:
