Internal energy is the total potential energy (from intermolecular forces) and kinetic energy (from particle motion) within a system due to the motion and interactions of its particles. In simple terms, it is the total energy in a system. Internal energy changes when heat is added or removed or when the system performs some work.

Thermodynamics is a part of physics that deals with the relationship between temperature, heat, energy and work. The Thermodynamics concept explains how energy is transferred in physical systems and how it affects matter. The laws of thermodynamics help in understanding phenomena like refrigerators, engines and even biological processes and govern these changes.

Class 11 Physics Waves is important for competitive exams like NEET and JEE, though it has moderate weightage. Students can check the weightage below;

  • In NEET, it usually covers about 2–3% of the Physics section, with 1–2 questions that are mostly theory-based, like the Doppler effect or wave speed.
  • In JEE Main, it makes up around 3–5%, with questions that are more numerical and application-based. JEE Advanced may include slightly more complex problems from this chapter.

Key areas like beats, standing waves, and wave equations are regularly asked. With proper understanding and practice, this chapter can help improve overall marks in

Class 11 Physics Chapter 14 Waves is very important for CBSE exams because it builds the foundation for many topics like frequency, wavelength, wave propogation, amplitude, wave equations. Chapter 14 Waves covers the types of waves, how they move, and important concepts like the superposition principle, standing waves, beats, and the Doppler effect. These topics often appear in exams as theory questions, derivations, or numericals. The chapter also helps in preparing for competitive exams like JEE and NEET. 

Questions from this chapter may carry 1, 3, or 5 marks, and often include diagrams and formulas in CBSE regular exams. To un

Students can check important formulae below;

  • The angular frequency? is related to the period and frequency of the motion by? =2? /T= 2?  
  • The particle velocity during SHM as functions of time are given by v (t) = –? Asin (? t +? )
  • The particle acceleration during SHM as functions of time are given by a (t) = –? 2 .A cos (? t +? )

A particle of mass m oscillating under the influence of Hooke's law restoring force given by F = – k x exhibits simple harmonic motion with

  • ? =? k/m
  • T= 2? m/k
  • T= 2? L/g

The Oscillations chapter in Class 11 Physics focuses on periodic motion, especially simple harmonic motion (SHM). It explains how objects move back and forth about a mean position and introduces important concepts like time period, frequency, amplitude, phase, and restoring force. This chapter is the foundation for wave motion and is widely used in both physics and engineering. NCERT Solutions simplify complex ideas and make problem-solving easier with step-by-step explanations.
