NCERT Solutions for Class 6th Science Chapter 11 – Light Shadows and Reflections

In CBSE Class 6 Science Syllabus of chapter 11, you will learn about Light, shadows and reflections.  It teaches you that light is a form of energy. It tells you that tiny energy packets of light are called photons.

It is the visible part of electromagnetic radiation having a wavelength of 400 to 700 nanometers. And, you can see the objects around you with the reflection of light that is when light strikes the object and reaches our eyes, we see the object. 

  • Transparent, Opaque and Translucent Objects

In this part of NCERT Class 6 Science Chapter 11 – Light Shadows and Reflections, you will learn about luminous and non-luminous objects. Here, you will understand how the objects are classified based on their interaction with light. 

For Example: 

  1. Sun and stars are luminous objects as they emit light. 
  2. Earth and trees are non-luminous objects as they do not produce light but will reflect the light emitted by luminous objects. 
  3. Glass is a transparent object. 
  4. Butter paper is a translucent object. 
  5. A book is an Opaque object. 
  • What are the Shadows? 

In this section of NCERT Solutions for Class 6th Science Chapter 11 – Light Shadows and Reflections, you will learn how shadows are formed and the various properties of shadows. Some Properties of shadows are given below.

  1. Shadow will require a screen to be formed such as a wall or ground. 
  2. Through shadow, you will be able to see the shapes of different objects. 
  • The Pinhole Camera

In this section of Class 6 Science Light Shadows and Reflections, you will learn a pinhole camera consists of a light-proof box, a thin layer for the purpose of the screen and a minute hole to pass the light rays. Here, you will learn how light entering from the small hole can form an inverted image on the screen. 

  • Mirrors

In this part of NCERT CBSE Class 6 Science Chapter 11, you will learn that a mirror is a surface which reflects the light incident by forming erect images. It is a surface which consists of glass.

  • Reflection

In CBSE NCERT Class 6 Science book, you will learn that the phenomenon of light bouncing back in the same medium after striking the surface of a smooth and shiny object is called reflection. Other important concepts covered in this section are as follows.

  • Incident ray:  The ray of light which falls on the surface of a plane mirror is called incident ray.
  • Reflected Ray: The incident ray after striking the surface of the mirror is sent back or reflected back into the same medium is called reflected ray.
  • Normal line:  The normal line is the perpendicular line drawn on to the surface of the mirror at the point of incidence.
  • The angle of incidence:  The angle made by the incident ray with the normal line at the point of incidence is called the angle of incidence or incident angle.
  • The angle of reflection:  The angle between the reflected ray and normal line at the point of incidence is called the angle of reflection or reflected angle.

Plane mirrors and images: 

In CBSE NCERT Class 6 Science Chapter 11, you will learn how to draw a ray diagram of an image formation. Below are steps that need to be followed.

  1. Place the object and mirror
  2. Draw the incident ray
  3. Draw the normal line at the point of incidence (90 degrees to the surface)
  4. Check the angle of incidence with the protector.
  5. Draw reflected rays in the same medium keeping the angle the same.

NCERT CBSE Class 6 Science Chapter 11 Exercise

Our NCERT Solutions for Class 6 Science consist of all questions of the exercise in detail. CBSE Class 6 Science Syllabus consists of only 1 exercise, which has 4 questions in it. 

  • Question 1 is an objective question type. In this, you will have to rearrange the given boxes. 
  • Question 2 is a short answer question. In this, you will have to classify the given objects or materials as transparent, translucent, luminous and non-luminous based on their characteristics. 
  • Question 3 is a diagrammatic question. It asks you to draw a shape that gives a circular shadow from one direction and a rectangular shadow from another. 
  • Question 4 is a short answer which is from the concept of the mirror.
