JEE Main Physics 2023: Important Notes for Session 1 exams

The JEE Main 2022 examination will be held in two sessions. Session 1 has been moved to June and will take place from June 20 to 29, while session two will take place from July 21 to 30. Every aspiring engineer’s dream is to be among the top scorers in the JEE Main exam. However, many students find it challenging to cover each topic from all three disciplines due to the extensive JEE Main syllabus. 

Many students find Physics difficult due to the numerical and theoretical concepts; however, it is a very scoring subject. We will discuss important tips, tricks, and high weightage chapters to focus on during your Physics JEE Main 2022 preparation. 

Make sure you don’t miss out on important dates and deadlines of your JEE Main 2022 examination.

Tips to Make Notes

Following are a few tips on how to make your revision notes for JEE Main 2022:

Prepare your notes

• It is not recommended that JEE Main aspirants copy or borrow notes. Notes can be made in any way that suits one’s needs and understanding.
• Preparing study notes might also help you comprehend the material better.
• Prepare JEE Main study notes on loose papers if at all possible.
• Assemble these stray documents into a file in an orderly fashion.
• This method of taking notes aids in effective exam preparation.

Keep everything close at hand

• Prepare JEE Main study notes on loose papers if at all possible.
• Assemble these stray documents into a file in an orderly fashion.
• This method of taking notes aids in effective exam preparation.

When you’re reading for the first time, don’t take any notes

• Making notes after the initial reading frequently results in a mess, with nearly the entire chapter highlighted.
• Aspirants should solely concentrate on learning the ideas after the first reading.
• After the second or third reading, make some notes.

The most important points should be highlighted

• This is based on a person’s understanding and preference.
• To mark points, use a variety of coloured highlighters.
• You can colour code concepts in yellow and key formulas in red.

Use Post-It Notes

• The JEE Main syllabus is extensive and takes time to finish.
• There can be significant gaps between visits to the same chapter, making learning more challenging.
• Sticky notes are very handy in these situations.
• Jot down crucial facts on these notes and tape them to the corner of relevant pages for easy memory.

 Make a list of your errors as well

• There are frequently challenging problems when tackling JEE Main Mock Tests and Previous Year Papers.
• Aspirants for JEE Main should keep track of such questions in their notebooks.
• Go over these questions again before taking the JEE Main 2022 exam.

 Aspirants for JEE Main 2022 can watch free video lectures

• Since last year, NTA has offered free content-based video lectures on their official website.
• Experts from IIT create these video lectures.
• These lectures assist applicants in preparing for the graduate-level engineering test, particularly those who cannot afford to attend coaching institutes.
• These videos can help you learn and revise for the JEE Main 2022 exam.

JEE Main 2022 Important Chapters for Physics

The list of key topics for JEE Main 2022 may be divided into low weightage topics and high weightage topics from Physics, Chemistry, and Mathematics. Following the advice of experts and using last year’s JEE Main exam papers, the syllabus was divided into two categories.

Examples of JEE Main 2022 Physics Important Questions

Question: The picture of an object created by a plano-convex lens at an 8-metre distance behind the lens is actually one-third the size of the item. The light inside the lens has a wavelength that is 2/3 that of light in open space. The lens’s curved surface has a radius of

1. 3m
2. 10m
3. 7m 
4. 9m

Answer: Given that- positive of image, v = +8

                                  magnification, m = 1/3

 m = v/u = 1/3

        8/u = 1/3 

        u = 8 * 3

        u = -24

μ = λ air / λ medium

λ air = 1 and λ medium = ⅔

So, μ = 3/2

According to the lens formula, 1/f = 1/v + 1/u 

where , 1/f = (u – 1) (1/R – 1/∞)

Substituting all the values we get R = 3m. Therefore the correct answer is (a) R = 3m.

Question: A wire’s resistance at 20°C room temperature is found to be 20W. Now, in order to increase the resistance by 20%, the wire must be heated to?

[The temperature coefficient of resistance of the wire material is 0.002 per °C].

(a) 176°C                 

(b) 124°C                

(c) 142°C                 

(d) 133°C

Answer: R1 = R0 (1 + αt)

At the beginning R0 (1 + 20α) = 20Ω

Finally, R0 (1 + αt) = 24 

At the beginning R0 (1 + 20α) = 20Ω

Finally, R0 (1 + αt) = 24

Now, 6/5 = (1 + αt) / (1 + 20α) 

Substituting all the values we get: 

5 + (5 x 0.002 x t) = 6 + 120 x 0.002

0.01t = 1.24

t = 1.24/0.01 = 124°C 

Hence, (b)b) 124°C is the correct answer. 

1. On the Celsius scale, the absolute zero temperature is

        0∘C

1. 32∘C
2. 100∘C
3. 273.15∘C

Answer: 

T = 273.15+t∘C 

⇒ 0 =273.15+t∘C

⇒ t =−273.15∘C

Hence, the correct answer is (d) 273.15∘C

1. The volume of a gas becomes four times if 

1. Temperature becomes four times at constant pressure
2. Temperature becomes one fourth at constant pressure
3. Temperature becomes two times at constant pressure
4. Temperature becomes half at constant pressure

Answer:

V∝T (as constant pressure)

Hence, the correct answer is (a) Temperature becomes four times at constant pressure.

Last-minute preparation tips

• Solving Previous Years’ Papers: Students should solve JEE papers starting in 2012 to gain a better understanding of the newest trends [since the JEE pattern has changed dramatically since the introduction of JEE(M) and JEE(Adv)] and the level of difficulty of the entrance exam. Before taking the entrance exam, students should complete at least 15-20 practice papers. Solving such exams in a timed manner helps you gain time management skills, which will improve your exam performance. Students can access the previous 14 years’ question papers on the Aakash website and detailed solutions. 
• Relaxed Mind: Before taking the exam, students are recommended to relax and have some fun or listen to music to relieve any fears or tensions they may have. A good night’s sleep and a clear mind are essential for getting the most out of your abilities.
• Have Faith in Yourself: The biggest thing you can do when taking JEE is to have faith in yourself. It would help if you were confident in passing the exam with a good score after all of your studying, preparation, and practice. Self-confidence allows you to win half of the battle. Going in with the intention of winning is a good idea. This unshakeable faith will undoubtedly result in success.
