NCERT Solutions for Class 12 Physics Chapter 10 Wave Optics

 

Let us start reading the preparation article Regarding CBSE 12 Class

NCERT solutions for class 12 Physics chapter 10 Wave Optics: Do you know that the Dutch Physicist Christiaan Huygens has put forward the wave theory of light in 1678? And this wave model will be discussed in this NCERT solutions for class 12 Physics chapter 10 Wave Optics. We have discussed in NCERT grade 12 physics chapter Electromagnetic waves that light is an electromagnetic wave. The wavelength of this electromagnetic wave is very small in comparison to the dimension of mirror or lens, so light is assumed to be traveled in a straight line. The NCERT class 12 chapter 10 Wave Optics starts with Huygens principle and derive the laws of reflection and refraction based on this principle. Other main topics discussed in NCERT solutions for class 12 Physics chapter 10 Wave Optics are the concept of diffraction and polarisation.

The main topics discussed in the chapter Wave Optics are listed below:

10.1 Introduction

10.2 Huygens Principle

10.3 Refraction and Reflection of Plane Waves Using Huygens Principal

10.3.1 Refraction of a plane wave

10.3.2 Refraction at a rarer medium

10.3.3 Reflection of a plane wave by a plane surface

10.3.4 The Doppler effect

10.4 Coherent and Incoherent Addition of Waves

10.5 Interference of Light Waves and Young's Experiment

10.6 Diffraction

10.6.1 The single slit

10.6.2 Seeing the single slit diffraction pattern

10.6.3 Resolving power of optical instruments

10.6.4 The validity of ray optics

10.7 Polarisation

10.7.1 Polarisation by scattering

10.7.2 Polarisation by reflection

The important derivations of  NCERT solutions for class 12 Physics chapter 10 Wave Optics are refraction and reflection using the Huygens principle. We can expect problems from youngs double slit experiment and single diffraction pattern from the class 12 Physics chapter 10.

NCERT solutions for class 12 Physics chapter 10 Wave Optics are explained below: 

Q-10.1 (a) Monochromatic light of wavelength 589 nm is incident from air on a water surface. What are the wavelength, frequency and speed of (a) reflected, Refractive index of water is 1.33.

Q- 10.1 (b) Monochromatic light of wavelength 589 nm is incident from air on a water surface. What are the wavelength, frequency and speed of (b) refracted light? Refractive index of water is 1.33.
