Teachers can guide you they can do 40% work. They can give u a direction, rest work is yours.
In Ray optics Total internal reflection is important topic. It’s one application optical fibre is there in syllabus of cbse board. So that’s important. You should know about critical angle n conditions for TIR.
Other important topics from ray optics is lens makers formula n numericals related to this.
Optical instruments Telescope n microscope both are important. Their ray diagrams for image formation at D n infinity are important. So always do written practice of Ray diagrams n their magnification.
Relation between angle of incidence & Angle of deviation is important.
Combination of lenses is also important for numericals.
For any doubt you can contact us. We will try to help you with in 1-7 days.
