Two identical straight wires are stretched so as to produce 6 beats/s when vibrating simultaneously. On changing the tension slightly in one of them, the beat frequency remains unchanged. Denoting by T1,T2 the higher and the lower initial tension in the strings, then it could be said that while making the above changes in tension.
JEE Advanced 2025 Exam Pattern
The JEE Advanced 2025 exam consists of two papers: Paper 1 and Paper 2. Both papers are compulsory and must be attempted by the candidates. The exam will be conducted online (computer-based).
Subject-wise Syllabus: JEE Advanced 2025
The JEE Advanced 2025 Subject-wise Syllabus covers crucial topics across Physics, Chemistry, and Mathematics, with each subject focusing on advanced concepts.
- Mathematics emphasizes Calculus and Algebra (accounting for up to 40% of the exam)
- Physics delves into Mechanics and Electrodynamics, while Chemistry includes topics like Physical Chemistry and Organic Chemistry.
- As observed from past data that Mathematics often carries the highest weightage, making it a critical area for focused preparation.
JEE Advanced Chapter-wise Weightage
The JEE Advanced chapter-wise weightage helps you understand which topics carry more importance in the exam. By focusing on high-weightage chapters, you can optimize your preparation. For example, in Mathematics, topics like Calculus and Algebra usually carry about 50-60% of the questions, while in Physics, Mechanics and Electromagnetism contribute significantly.
JEE Advanced Physics - Weightage and Important Topics
| Topic | Approximate Weightage | Important Topics |
|---|---|---|
| Mechanics | 20-25% | Kinematics, Laws of Motion, Work, Energy & Power, Rotational Motion |
| Thermodynamics | 8-12% | First and Second Laws of Thermodynamics, Entropy, Heat Transfer |
| Electrostatics and Magnetism | 15-18% | Coulomb’s Law, Electric Fields, Gauss’s Law, Ampere’s Law, Magnetic Field due to Currents |
| Modern Physics | 10-15% | Photoelectric Effect, Atomic Models, Nuclear Physics, Semiconductors |
| Optics | 8-10% | Reflection & Refraction, Wave Optics (Interference, Diffraction) |
| Properties of Matter | 5-8% | Elasticity, Surface Tension, Viscosity |
| Gravitation | 5-7% | Gravitational Force, Potential Energy, Kepler’s Laws |
- Mechanics (particularly Kinematics and Laws of Motion) have a higher weightage, often constituting a major chunk of the Physics paper.
- Modern Physics, with topics like the Photoelectric Effect and Nuclear Physics, remains significant with high-scoring potential.
- Physical Chemistry and Organic Chemistry both have a large weightage. Topics like Chemical Kinetics and Reaction Mechanisms in Organic Chemistry are crucial and frequently asked.
- Inorganic Chemistry remains a reliable scoring area with an emphasis on Periodic Table and Coordination Compounds.
JEE Advanced 2025: Subject-wise Weightage
| Subject | Weightage | Important Topics |
|---|---|---|
| Physics | 25-30% | Mechanics, Electrostatics, Magnetism, Modern Physics, Thermodynamics |
| Chemistry | 25-30% | Physical Chemistry, Organic Chemistry, Inorganic Chemistry |
| Mathematics | 35-40% | Algebra, Calculus, Coordinate Geometry, Trigonometry, Probability |
- Mathematics holds the highest weightage, so mastering Calculus and Algebra is critical.
- Physics and Chemistry both have significant portions dedicated to Mechanics and Physical Chemistry, respectively.
- Regular practice of important topics like Modern Physics, Organic Chemistry, and Coordinate Geometry can help candidates maximize their scores in JEE Advanced 2025.
To find the Minimum Marks Required to Qualify JEE Advanced 2025, it's also important to understand the category-wise cutoff criteria set by the exam authorities.
