Chapter 11 – Human Eyes and Colorful World
C.B.S.E. Class 10 Science Chapter 11 "Human Eye and Colorful World" taught under Physics is a continuation of Science chapter 10 Light Reflection and Refraction through which students would learn about the optical phenomenon. Chapter 11 also discusses the blue colour of the sky, how a rainbow is formed and what makes a white light split. In this chapter, students would get to know the meaning of accommodation of the eye, which means the ability of the eye to see both near and distant objects just by adjusting its focal length. The chapter also talks about the near point of the eye definition or the meaning of the least distance of distinct vision, which is nothing but the smallest distance at which a human eye can see objects without any strain. Then, the chapter Human Eye and Colorful World-Class 10 discusses the common refractive defects of vision that include myopia, hypermetropia, and presbyopia. Towards its end, the chapter throws light on dispersion, which occurs when the light splits into its component colours. And, it also informs the students about the fact that the factor responsible behind the blue colour of the sky and reddening of the Sun at sunrise and sunset is scattering of light.
The above summary on Chapter 11 Human Eyes and Colorful World is further classified into six topics, which are briefed below:-
11.1 The Human Eye
In this topic, the chapter explains the importance of the Human Eye, its functions and its structure. Out of all the five sense organs a human being has, the human eye is the most sensitive and precious sense organs. Through it, a human being can see the beautiful and colourful world around him. The topic also talks about the human eye lens and the power of accommodation.
11.2 Defects of Vision and Their Correction
The second topic briefs about the defects of vision and how they can be corrected. The topic discusses the three most common refracted defects of the eye, which are myopia meaning near-sightedness, hypermetropia meaning far-sightedness and lastly presbyopia meaning the decreasing ability of the eye to focus clearly on small objects. The chapter explains how using a suitable spherical lens can correct these defects of vision.
11.3 Refraction of Light through a Prism
In the third topic "Refraction of Light through a Prism", students would learn to refract the lights through a triangular glass prism with the help of activity clearly explained in NCERT Solutions Class 10 Science Chapter 11.
11.4 Dispersion of White Light by a Glass Prism
In this topic, students will learn about the process of formation of the rainbow by performing an activity. This activity relates to the refraction light through a prism, which is also the reason why white light disperses by a glass prism.
11.5 Atmospheric Refraction
Here, the chapter tells about the meaning of Atmospheric Refraction and how the twinkling of stars and advanced sunrise & delayed sunset are associated with it. In this topic, it is said that because of atmospheric refraction of starlight stars twinkle at night.
11.6 Scattering of Light
This topic explains the whole Tyndall Effect, the reason behind the blue colour of the sky and why the colour of the Sun is red at the time of sunrise and sunset.
