In this Article you can download Handwritten Notes of Ray Optics NCERT solution Class 12 Physics. Ray Optics is one of the most important Chapter of Class 12 Physics. Solution which we are providing is with diagram to provide a clear Explanation of Questions. We tried our best to prepare these notes.
How to Solve Numericals in Physics?
• Firstly read Statement of Question at least 2 times with full Concentration.
• Then write the given data & Underline what you have to find out?
• After that any data which is not in S. I system means which you have to convert in other system.
• To Solve Question think about formula which you can apply & Try to solve question Yourself then draw diagram if you can according to question. It will help you to solve Questions in Ray Optics.
• After solving Questions you can check your answer. If your answer is correct that’s okey. If not then Check solution. This is the correct way to solve Numericals.
• Never use calculator to solve question because in exam there will be no calculator. So avoid that. Do Calculation work your self it will Boost your Calculation Speed.
Content Of Ray Optics:
Reflection of Light, Spherical mirrors, Mirror Formula, Refraction of Light, Total Internal Reflection and Optical fibers, Refraction at spherical surfaces, Lense, Thin lens formula, lens Maker’s Formula, Magnification, Power of a lens, Combination of thin lense in contact, Refraction of light through a
prism. Optical instruments: Microscope & Astronomical Telescopes ( Reflecting & Refracting) & their Magnifying Powers.
Important Topics Of Ray Optics
Total Internal reflection & Optical Fiber
lens Makers Formula Derivation & Numericals related to this.
Refraction of light Through a prism ( Derivation & Numericals Related to this Topic)
Optical instruments ( Microscope & Telescope Both are equally Important. In optical instruments questions related to their magnifying power can come. One question of case study can come from this chapter. In 2023-24 there was one question of case study from this chapter.
So this Chapter is important to score better in Physics.Now how you can Prepare this Chapter for Board Exams?
