Hi Sarthak,
Sonar is an acoustic wave (whose uses are roughly analogous to radar) and whose name is an acronym for "sound navigation and ranging." Sonar consists of pulses of sound waves are transmitted into water, usually at ultrasonic frequencies in the range of 20-100 kHz. They travel out and are reflected by a solid object. The reflected signals are detected and then correlated to give the operator an indication of the distance and bearing of the object.
There are some fundamental differences to note between sonar and radar. First, the frequencies used for sound are much lower, since sound is highly attenuated at frequencies higher t

I have 3 subjects in my graduation (B.Sc) Physics, Maths and Chemistry, I am confused about what subject should I prepare for in IIT JAM?

Rakshit Prabhakar

Well, if you have Physics, Chemistry, and Mathematics, all three in your Bachelor's degree you should first understand and analyze that which subject you like the most and you are highly interested in. Then devote atleast a year and evaluate the scope of M.Sc in that particular subject, study it and then select the subject. Don't be in a rush, take your time.

What are some books to prepare for JEE Advanced physics?

Mamta Bankoti

Well, that's great, as you are preparing for JEE Advanced Physics. From my research, I would like to recommend some of the books and resources that will help you learn the basics and understand the concept:

1. Concept of Physics (Vol 1 and 2) by H.C. Verma

2. Understanding Physics Series by D.C. Pandey (Arihant)

3. Fundamentals of Physics by Halliday, Resnick and Walker

4. Problem in General Physics by I.E Irodov

5. Physics Galaxy by Ashish Arora.

6. Previous Year Question Book (likee PW 48 Years/Oswaal JEE Advanced Paper)

5. Physics Galaxy by Ashish Arora.

6. Previous Year Question Book (likee PW 48 Years/Oswaal JEE Advanced Paper)

The first book to read would be 'Concepts of Physics (vol 1 and 2)' by H.C. Verma Why you should read this book first: because it will build strong basics, and you will understand the concept easily. This book explains each and every topic in simple language and helps you to learn problems step by step.

After that, you can read the 'Understanding Physics Series' by D.C. Pandey (Arihant). This book is divided into 5 parts (Mechanics 1, Mechanics 2, Waves and Thermodynamics, Electricity and Magnetism, and Optics and Modern Physics). This book has a lot of JEE Main and Advanced level questions that will help you to practice every type of problem.

The third book to read is 'Fundamentals of Physics' by Halliday, Resnick, and Walker. This book gives you a deep understanding of theory and helps you with the physics concept. This book will improve your theory and alternative methods.

The fourth book you can read is 'Problem in General Physics' by I.E. Irodov. This book has one of the toughest problems for JEE Advanced. This book helps you to develop speed and accuracy.

The fifth book you can read is 'Physics Galaxy' by Ashish Arora. This book covers all the conceptual gaps that you will not find in other books and contains advanced illustrations and tricky problems.

The last book would be 'Previous Year Question Book (like PW 48 Years/Oswaal JEE Advanced Paper).' This book helps you to understand the real exam patterns. You will get to know how the questions are asked, and you will learn how to apply what you have learned. It will not only improve your timing but also build confidence in you.

I hope this will help.
