! Here's an outline for a Geometric Optics Short Notes PDF tailored for JEE Mains and Advanced preparation. This document provides a concise yet comprehensive overview of the key topics in geometric optics.
Geometrical optis

Light is not visible of incident light falls
2 Objects are visible with converging on it its objectis
the help of light To see an virtual At a point where
object light must enter light would have converged
our eyes An object will
appear at a point from V0
which light appear to
diverge into our eyes
of Reflected Transmitted
If light converges ats
image
is real At a point where
I light would converge
3 An optical device simply
bends the light f RI
Every optal devicehas
its own obseet forms of Reflected Transmitted
its own amage light Diverges As image
of incident light falls is virtual a point from
At
diverging on it its object where light appears to diverge
is Real At a point from
which light diverges or
