#rayopticsclass12 #exampleproblems A thin biconvex lens is made up of a glass of Refractive index 1.5. The two surfaces have equal radii of curvature of 30cm each. One of its surfaces is made reflecting by silvering it from outside. (a) What is the focal length and Power of this silvered lens? (b) where should an object be placed in front of this lens so that the image is formed on the object itself? _______________________________________________ Ln-6 ( Ray optics) https://youtube.com/playlist?list=PLZGuOVrLM03pn5SATAaJVoR5yriqtv0W7&si=sr4og8JgBVQhx28Q Example Problem Ln-1 https://youtube.com/playlist?list=PLZGuOVrLM03p7hLBS0ufspCKJ3N3qY-jC&si=AwGWAE4umODV8fYL Ln-2 https://youtube.com/playlist?list=PLZGuOVrLM03oRUkl-2DEoQMne6E6oTsEK&si=5r_3f6rqG5Y8RH0M Ln-3 https://youtube.com/playlist?list=PLZGuOVrLM03rLnmHOwNpUMS5LVr5zh8JD&si=EL355__984CewzXR Ln-4 https://youtube.com/playlist?list=PLZGuOVrLM03qDHkaMKeKnNFFgBXUnVC6P&si=sFD4yjr8ASMkRzI1 Ln-5 https://youtu.be/NngVraGMi2Q?si=WNb71hwEqG7565Uc ************************************************ Telegram : https://telegram.me/mokka_physics Instagram: https://www.instagram.com/inbaraj_sir __________________________________________________________________________________________ #11th12thphysicsintamilexplanation #exampleproblems #mokkaphysics #bookbackonewords #inbarajsirphysics #ncertphysicsintamil #physicsshortandquickexplanationintamil #physicspracticalvideos
