NCERT Solutions for Class 10 Science, Chapter 11 - The Human Eye and the Colourful World

Have you ever wondered why the sky appears to be blue or why the rainbow has seven
colours? In the previous chapter, you got a clear idea about refraction of light and
formation of images by lenses. In this chapter, we will go a step ahead and study the
human eye in detail. After all, the principles applied in refraction through lenses can
easily be applied in the functioning of the human eye. You will also learn about various
defects in the human eye and how these defects are corrected.

A thorough study of NCERT Solutions for Class 10 Science, Chapter 11 will give you
a clear understanding of basic questions related to nature and the human eye.

Let’s take a look at topics and sub-topics of Class 10 Science Chapter 11, The Human Eye and the Colourful World

11.1 The Human Eye
11.1.1 Power of Accommodation
11.2 Defects of Vision and their Correction
11.3 Refraction of Light through a Prism
11.4 Dispersion of white light by a glass prism
11.5 Atmospheric Refraction
11.6 Scattering of Light
11.6.1 Tyndall Effect
11.6.2 Why is the colour of the clear sky blue?
11.6.3 Colour of the sun at sunrise and sunset

In Class 10 Science Chapter 11, you will learn – 

Section 11.1 – In this section, you’ll study the structure of the human eye, how the
the human eye works like a camera, and how it helps us see the beautiful world around us.
You’ll also learn about various parts of eyes such as the pupil, retina, cornea, iris,
aqueous humour, crystalline lens, optic nerve and more.

Section 11.2 – In this section, you’ll learn why vision becomes weak and blur, various
refractive defects such as myopia or near-sightedness, hypermetropia or farsightedness,
and presbyopia. You’ll also learn how lenses help in correcting these defects.

Section 11.3 – In this section, you’ll study what happens when the light gets refracted
through a prism. You’ll also come across related terms like the angle of the prism.

Section 11.4 – In this section, you’ll acquire knowledge about the dispersion of white
light by a glass prism. You’ll also learn what white light is, recombination of the
spectrum of white light, dispersion of light and why the rainbow has seven colours.

Section 11.5 – In this section, you’ll study atmospheric refraction. You’ll learn why stars
twinkle at night and what happens in advance sunrise and delayed sunset.

Section 11.6 – In this section, you’ll learn what scattering of light is, Tyndall effect, why
the sky is blue in colour and what happens to the colour of the sun at sunrise and
sunset.

In this chapter, you are provided with several diagrams, activities and examples with
their solutions for a clear understanding of The Human Eye and the Colourful World.
