Physics is not just about machines, energy, or motion. It also explains many amazing things we see in our daily lives—like why the sky appears blue, or why we see a rainbow after it rains. Chapter 6 of Class 10 Physics, titled "The Human Eye and the Colourful World," explores these wonders in a fun and easy way. This chapter helps students understand how our eyes work and how light plays tricks to create beautiful effects in nature.
Lakhmir Singh’s solutions are designed to make learning easier and more enjoyable for students. The book provides detailed explanations and answers for every question in the chapter. These solutions are simple to understand and follow a step-by-step method, so even difficult topics feel easy. Whether it’s about the structure of the human eye or the science behind rainbows and scattering of light, these solutions guide you clearly through each concept.
In this chapter, students learn how the human eye helps us see the world. It explains parts of the eye like the cornea, lens, retina, and optic nerve, and how they work together to form images. It also talks about interesting ideas like the power of accommodation—how our eyes adjust to see near and far objects—and common eye problems like myopia and hypermetropia, including how to correct them using lenses.
Another exciting part of this chapter is about the colorful world around us. Why is the sky blue? Why do sunsets appear red? How does a prism split light into seven colors? These everyday wonders are explained using easy experiments and logic. The chapter also introduces the concept of atmospheric refraction, which helps us understand effects like the twinkling of stars and the formation of rainbows.
Lakhmir Singh Solutions help students prepare for exams by offering clear explanations, solved numericals, important definitions, and extra tips. They are very useful for understanding NCERT concepts, practicing for school exams, and building a strong base in Physics.

Q1. What type of lens is found in the human eye?
Ans. The human eye has a convex lens.
Q2. Name two parts of the eye that bend light rays.
Ans.The cornea and the eye lens bend light rays.
Q3. Name the part of the eye:
a) That controls how much light enters the eye
b) Where the image is formed
c) That changes the lens shape to adjust focus
Ans.
a) Iris
b) Retina
c) Ciliary muscles
Q4. What is the name of:
a) The curved, clear front part of the eye?
b) The part of the eye that senses light?
Ans.
a) Cornea
b) Retina
Q5. Where is the image formed in the human eye?
Ans. The image is formed on the retina.
Q6. What does the eye lens do?
Ans. The lens changes shape to focus light on the retina.
Q7. What does the pupil do in the eye?
Ans. The pupil becomes bigger or smaller depending on the light around us.
Q8. How does the eye react to more brightness?
Ans. The pupil gets smaller when there is more light.
Q9. Which part of the eye acts like the film in a camera?
Ans. The retina acts like the film in a camera.
Q10. Which part of the retina does not sense light?
Ans. The blind spot does not sense light.
Q11. Which part of the eye has light-sensitive cells?
Ans. The retina has cells that sense light.

Q12. What are the two types of cells in the retina that sense light?
Ans. Rods and cones are the two types of cells.
Q13. Among rods and cones:
a) Which one sees color?
b) Which one works in low light?
Ans.
a) Cones
b) Rods
Q14. True or False: The image formed on the retina is upside-down.
Ans. True
Q15. What is the main function of the eye lens?
Ans. To focus light on the retina.
Q16. Where does most light bending happen in the eye?
Ans. At the cornea.
Q17. What changes the shape of the lens?
Ans. The ciliary muscles change the lens shape.
Q18. What do the ciliary muscles do when looking at something close?
Ans. They make the lens thicker.
Q19. What is the closest distance a normal eye can see clearly?
Ans. 25 cm
Q20. What is the:
a) Far point of a normal eye?
b) Near point of a normal eye?
Ans.
a) Infinity
b) 25 cm
Q21. What is the range of clear vision for a normal eye?
Ans. From 25 cm to infinity.
Q22. Which part helps us quickly focus on near and far objects?
Ans. Ciliary muscles
Q23. What is meant by "power of accommodation"?
Ans. It is the eye's ability to focus on both near and far objects by changing the lens shape.
