Optics, due to its contemporary nature, tends to deter students from reading it. From this topic, generally, 2 or 3 questions appear in the JEE Main exam and around 3 in JEE Advanced. This means that it would be unwise to skip or postpone mastering this topic. Some regard this as one of the easiest topics to learn. But like all things, nothing is easy. It only becomes so if you can dedicate yourself towards it. Some teachers outstandingly teach this topic. That way a lot of students will learn it easily. But not everyone goes to a coaching center, and even if they did, they might not understand completely what the teacher is teaching.
Here are the subtopics that come under Optics:
- Rectilinear Propagation of Light: This introduces you to the basics of the topic. You will learn about the theories and the basic formulas for light. Along with this, you will learn about the electromagnetic spectrum.
- Reflection and Refraction: Here, you will learn about the properties of reflection and refraction of light through plane and spherical surfaces. You will also learn about total internal reflection and how it occurs.
- Prism: In this subtopic, you will learn about the dispersion and deviation of light when it passes through a prism.
- Lenses and Thin Lenses: Convex and concave lenses, their properties, and problems related to this.
- Combination of lenses and mirrors: Different combinations of lenses and spherical mirrors and how they affect the light passing through it will be dealt with here. Only when you are through with the above topics should you attempt to learn this, as a solid understanding of them is required.
- Magnification: The very basic concepts of magnification
- Wave Nature of Light: This can be considered as a separate topic but falls as a category under optics. You will learn about Huygens’ theory of light and the young’s double-slit experiment. This is an interesting topic and is easy to master.
Hence, it is essential that regardless of how the student is preparing for the exam, you must do it right. So,
- The first thing you have to do is to get the right material. So the first thing you have to get is the NCERT Books. These books are a must-have for all aspirants. Then get yourself some other material like HC Verma. Then you are all set.
- After learning each concept, try out problems to solidify your understanding. This will make sure no stone will be left unturned.
- After you think you have learned all the concepts, then take mock tests specifically only on the optics part of JEE Main and JEE Advanced. Then you can know where you stand in terms of your preparation.
- Keep a friend with whom you can talk about and discuss the problems together. This would be good if you are learning together. This way, you can take mock tests together, and having a friend will always be a motivating factor where you will feel you can continuously push yourself to be better.
