CBSE NCERT Class 10 Science Chapter 11

This segment of NCERT Solutions for Class 10 Science Chapter 11-The Human Eye and the Colourful World, educates you about one of the most complex organs of the body the human eye. 

  • The Human Eye

Here, the chapter talks about various parts of the eye such as Retina, Cornea, pupil, ciliary muscles aqueous humour, optical nerve and Iris. You will also learn the functions of the various eye parts. Here you will be taught about the real and inverted image which is formed on the retina. You will also understand how the brain receives signals from the light-sensitive cells.

  • Power of Accommodation

This part of NCERT Class 10 Science Chapter 11, discusses how eye lenses use focal lense to increase and decrease the objects based on the distance. Near point and far point of the eyes are also a part of this concept. 

  • Defects of Vision and their Correction

This section of the chapter educates you about three common defects of vision. You will learn what myopia, hypermetropia, cataract and presbyopia are. You will also learn about how each of the vision defects can be corrected. 

  • Dispersion of White Light by a Glass Prism

In Class 10 Science The Human Eye and The Colourful World shall teach you how white light which passes through a prism splits into a band of colours. Spectrum is the band of colours. In the other part of the chapter, you will read about the Refraction of Light Through a Prism, prism, angle of the prism, angle of deviation, dispersion of white light through a glass prism, composition of white light, polychromatic light, recombination of white light rainbow and formation of the rainbow.  

  • Atmospheric Refraction

This segment of Class 11 Science The Human Eye and the Colourful World, focuses on what is atmospheric refraction and various concepts and how it plays an important role in different phenomenons.

  • Twinkling of Stars

Here you will learn that the twinkling of stars happens through refraction, which takes place when the light enters the atmosphere.  

  • Advance Sunlight and Delayed Sunset

This chapter teaches you that due to the atmospheric refraction, the sunrise is visible 2 minutes before the sunrise and sunset will appear after the 2 minutes of the actual sunset. 

  • Tyndall Effect

In NCERT CBSE Class 10 Science Chapter 11 you will come to know that when a beam of light strikes the minute particles of the earth’s atmosphere, molecules of air and the dust particles, then the beam path becomes visible. This scattering of light causes the Tyndall effect. 

This chapter also teaches you why the sky appears to be blue.
