Summary of NCERT Solutions for Class 10 Science Chapter 11 : Human Eye and The Colourful World :
In this chapter, we covered all the topics related to eye.
Eye is an optical instrument which is used to seeing the object.
The accommodation of the eye is the ability of the eye to focus on both near and far objects by changing its focal length.
The shortest distance at which the eye can see objects clearly without exertion. It is around 25 cm for a young adult with normal vision.
Short-sightedness (myopia) occurs when the image of distant objects is blurred. The image of distant objects is focused before the retina adjusted with an appropriate concave lens.
A convex lens of appropriate power is used to correct hypermetropia (far-sightedness )— the picture of adjacent objects is focused beyond the retina).
The eye's ability to accommodate changes with age.
The process of breaking of white light into its component colours is called dispersion.
At the time of sunrise and sunset, Due to scattering of light the sky looks red during the sunrise and sunset and blue at noon .
The structure of the human eye is described in NCERT Solutions For Class 10 Science Chapter 11. Our experts also explain why the sky appears to be different colours at sunrise and sunset. It also refers to the eye’s closest point or the shortest distance at which distinct vision may be seen.

In this chapter OSWAAL experts explain about the vision defects and their correction. There are three types of vision defects in the human eyes . These are following:
By the use of suitable spherical lenses we correct our vision defects.
11.3 Light Refraction Through a Prism
In this chapter OSWAAL experts explain about the refraction of light through prism . You now understand how light is refracted by a rectangular glass slab. When the ray of light is passed through the prism then they split into their constituents colours . By the help of an activity, you will learn how light is refracted through a triangular glass prism in this topic.
11.4 Dispersion of White light
In this chapter OSWAAL experts explain about the dispersion of white light vis glass prism. In this process the white light pass through the glass prism and split into their constituents colours formed on spectrum is called dispersion of light. In this topic our experts also explain about the formation of rainbow. It will also help you in understanding why the white light is dispersed by a laser.
11.5 Atmospheric Refraction
In this chapter OSWAAL experts explain about the Atmospheric Refraction. In this topic we cover many subtopics likes as why star twinkle is the night . Why sky look red during the sunrise and sunset and many more.
11.6 Scattering of Light
In this chapter OSWAAL experts explain about the scattering of light.
A beam of light passes through the true solution does not have a visible path. However, in a colloidal solution, where the particle size is substantially greater, its path becomes visible. The Tyndall Effect is also discussed in this topic
