## DC Pandey Solutions for Optics and Modern Physics: Chapter-wise

DC Pandey Optics and Modern Physics Book consist of 6 chapters on the whole. They have been briefly discussed below.

## DC Pandey Reflection of Light Solutions (Chapter 26)

Reflection of Light of DC Pandey Physics book will introduce you to the nature of light, a few general points of geometric optics and reflection of light. Here you will understand various types of reflection of light such as regular reflection which is also known as specular reflection, diffuse reflection and multiple reflections.

This chapter also teaches you that the angle of incidence is also a part of the reflection of light. Here you learn that the ray of light that hits the polished surface is called the incident ray, the ray that gets reflected away is called the reflected ray, the point at which the light hits the surface is called the point of incidence, and if a line is drawn perpendicular to that point, it is called the normal.

Chapter 26 also throws light upon regular reflection, irregular reflection, laws of reflection formula, angle of reflection and calculation of the angle of incidence and angle of reflection. This chapter also teaches you about the formation of an image by a plane mirror, reflection of light from a spherical mirror,

The exercises at the end of the chapter comprise 3 introductory exercises with 11 questions, 16 subjective questions (level 1), 13 objective questions(level 1), 10 assertion and reason questions, 20 objective questions (level 2), 5 match the columns questions and 5 more than one option is correct questions. On the whole, there are around 80 questions. Our DC Pandey Electricity and Magnetism Solutions are prepared by expert Physics teachers and answer all questions in a stepwise, accurate and precise manner.
