FAQs on 5 Days Timetable: The Human Eye and the Colourful World - Science Class 10

1. What are the main parts of the human eye and their functions?
Ans. The main parts of the human eye include the cornea, pupil, iris, lens, retina, and optic nerve. The cornea helps to focus light, the pupil controls the amount of light entering the eye, the iris gives the eye its color and regulates the pupil size, the lens further focuses light onto the retina, which converts light into electrical signals. The optic nerve transmits these signals to the brain, allowing us to perceive images.
2. What is the power of accommodation in the human eye?
Ans. The power of accommodation refers to the ability of the eye to change its focal length to focus on objects at different distances. This is achieved by the eye's lens changing shape, becoming thicker to focus on nearby objects and thinner for distant objects. This process allows us to see clearly at various distances.
3. What are common defects of vision and how can they be corrected?
Ans. Common defects of vision include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Myopia can be corrected with concave lenses, hyperopia with convex lenses, and astigmatism with cylindrical lenses. Regular eye examinations are essential for diagnosing these conditions and prescribing the appropriate corrective lenses.
4. How does light refract through a prism and what is dispersion?
Ans. When light passes through a prism, it bends or refracts due to the change in medium from air to glass. This bending occurs at the surfaces of the prism, separating white light into its constituent colors - red, orange, yellow, green, blue, indigo, and violet - a phenomenon known as dispersion. Each color bends at a different angle, resulting in a spectrum.
5. What is atmospheric refraction and how does it affect our perception of objects?
Ans. Atmospheric refraction is the bending of light rays as they pass through different layers of the Earth's atmosphere, which have varying densities. This phenomenon can cause objects like stars to appear higher in the sky than they actually are and can also create effects like the apparent change in position of the sun during sunrise and sunset. It plays a significant role in how we perceive celestial bodies.
