Class 10 Science Chapter 10 MCQ : The Human Eye and the Colourful World MCQs Quiz
Chapter 10, The Human Eye and the Colourful World, begins by explaining the construction and working of the human eye, detailing the function of the cornea, pupil, crystalline lens, retina, and optic nerve. It describes the power of accommodation and how the eye adjusts focal length. The chapter then discusses common defects of vision—Myopia (near-sightedness), Hypermetropia (far-sightedness), and Presbyopia—along with their correction methods using lenses. Finally, it explores natural optical phenomena: Refraction of Light through a Prism, Dispersion (splitting of white light), Atmospheric Refraction (twinkling of stars, advanced sunrise/sunset), and Scattering of Light (blue color of the sky, red sunsets, and the Tyndall effect).
Conclusion
Understanding Class 10 Science Chapter 10 is essential for grasping the principles of optics and their application in daily life. By attempting this Human Eye and Colourful World Class 10 MCQs Quiz, you have tested your knowledge of how we see the world and how light behaves in the atmosphere. Regular practice of these Class 10 Science Chapter 10 Quiz questions will help you differentiate between dispersion and scattering and memorize the corrective lenses for vision defects.

FAQs (Frequently Asked Questions)
- What is the function of the retina in the human eye?
The retina acts as a light-sensitive screen. It receives light rays focused by the lens, converts them into electrical signals, and sends them to the brain via the optic nerve. - What is Myopia (near-sightedness)?
Myopia is a vision defect in which a person can see nearby objects clearly but cannot see distant objects distinctly. It is caused by the elongation of the eyeball. - Which lens is used to correct Hypermetropia (far-sightedness)?
A convex lens (converging lens) of suitable power is used to correct Hypermetropia. - What happens during the dispersion of light?
Dispersion is the splitting of white light into its component colors (VIBGYOR) when it passes through a glass prism. - Why does the sky appear blue to us?
The sky appears blue because the atmosphere scatters blue light (shorter wavelength) more effectively than red light. - Name the phenomenon responsible for the twinkling of stars.
Atmospheric refraction is the phenomenon responsible for the twinkling of stars. - What is the Tyndall Effect?
The scattering of light by colloidal particles (like dust, smoke, or water droplets) in the atmosphere, making the path of the beam visible, is called the Tyndall Effect. - What is the blind spot of the eye?
The blind spot is a small region at the junction of the optic nerve and the retina where no photoreceptors (rods and cones) are present, so no image is formed at that spot. - Why do we see the sun a little before it actually rises and a little after it sets?
This is due to atmospheric refraction. Light rays coming from the sun bend slightly towards the normal as they pass through the atmosphere, making the sun appear slightly higher than its actual position. - What is the function of the Ciliary muscles?
Ciliary muscles hold the eye lens in position and help in changing the focal length of the lens by altering its curvature, which enables us to focus on near and distant objects.
