These notes are prepared by experts having years of experience by analyzing the CBSE marking scheme. In the NCERT Solutions Class 12 Physics Chapter 10, all minute detail and apt knowledge about the following topics are included:

10.1 Introduction

Ch 10 Physics class 12 is based on the wave theory of light. The chapter has a detailed explanation of refraction and reflection of waves with the help of the Huygens Principle, coherent and incoherent addition of waves, interference of light waves, and validity of ray optics. 

Students will learn the following topics in the NCERT Solutions Class 12 Physics Chapter 10: 

• Huygen’s principle 
• Derivation of laws of reflection and refraction
• Interference based on the superposition principle
• Diffraction based on the principle of HuygensFresnel 
• Polarization

10.2 Huygens Principle

Before studying the Huygens Principle, there is a simple introduction of wavefront and its types based on the shape of the source of light, i.e. Spherical and Cylindrical wavefront. Students are introduced to Huygens’s Principle and its assumptions in this section. The NCERT Solutions Class 12 Physics Chapter 10 includes many numerical questions depending on the relation between intensity and amplitude. 

10.3 Refraction And Reflection Of Plane Waves Using Huygens Principle

Under this section in the Class 12 Physics chapter 10 NCERT solutions, students will learn about refraction of a plane wave, refraction at a rarer medium, reflection by a plane surface, and the Doppler Effect. These derivations are often asked in exams. 

The concepts included in this sector are explained in detail in the NCERT Solutions Class 12 Physics Chapter 10. Students are advised to focus on this section to understand the next concepts easily. 

10.4 Coherent And Incoherent Addition Of Waves

Based on the above topic, students learn the theory of the interference pattern produced by

the superposition of two waves. Students also learn the difference between Coherent And Incoherent waves. To understand this section, students should recall the superposition principle explained in the NCERT Solutions Class 11. The step-by-step and detailed explanation of the derivation will help students perceive the concept better to attempt all related questions in the exam.

Students are advised to use the chapter 9 Physics class 12 NCERT solutions to significantly enhance their understanding and learning process.

10.5 Interference Of Light Waves And Young’s Experiment

This section of NCERT Solutions Class 12 Physics Chapter 10 includes brief information about the Interference of Light. They also learn about the different types of interference, such as constructive and destructive interference. The resultant topic intensity due to two identical waves gives the relation between intensity for two coherent sources. Under this section, students have to solve various sums based on average intensity and the ratio of maximum and minimum intensities. The Young’s Double Slit Experiment includes a discussion of various topics like path difference, bright fringe, dark fringe, and Shifting of Fringe Pattern in YDSE. 

Here are some of the formulas included in this section:

• Width of one fringe: =Dd
• Fringe width  ∝ 1d where d is the separation between the sources
• Position of nth bright fringe from central maxima: xn =nDd = n
• Position of nth dark fringe from central maxima: xn =(2n-1)Dd = (2n-1)2

10.6 Diffraction

This section in NCERT Solutions Class 12 Physics Chapter 10 helps students understand the phenomenon of diffraction and its types, i.e. Fresnel and Fraunhofer Diffraction. It further includes the Single Slit, seeing the Single Slit Diffraction pattern, Resolving Power of optical instruments, and the validity of Ray Optics. In addition, students will learn more about the Objective lens of instruments like telescopes or microscopes. Sums based on angular half-width of Airy disc and the lateral width of the image will be asked in the exams. 

10.7 Polarisation

Students will get a clear understanding of polarisation by Scattering and Reflection. Concepts like polarised light, polaroid, and Fresnel distance have been explained lucidly. Then, with the help of the NCERT Solutions Class 12 Physics Chapter 10, students will learn about Brewster’s law which gives the relationship between the angle of polarization and refractive index and Malus law.
