A person standing at point Y is watching a car coming from a point X to O as shown.The table shows the variation in the parts of eye while seeing the car at X and O. 1. At the X focal length is higher than at O 2. At O focal length is higher than at X 3. At X cilliary muscle is thicker than at O 4. At O cilliary muscle is thicker than at X *
Answers
Answer :
Based on the given information, option 2 is correct: "At O focal length is higher than at X."
This is because the focal length is the distance between the lens of the eye and the retina, and it is adjusted by the ciliary muscle. The thicker the ciliary muscle, the shorter the focal length and vice versa. According to the table, the eye's refractive power (inverse of focal length) is higher at O than at X. This implies that the ciliary muscle is thinner at O than at X, which is consistent with the fact that the focal length is higher at O.
Explanation :
Based on the information given in the table, it can be concluded that statement 2 is correct: at O, the focal length is higher than at X. Focal length is the distance between the lens and the point where the light rays converge to form a focused image. A higher focal length means that the lens is more powerful, and the image is formed at a greater distance from the lens. Since the person is watching the car moving away from them, the image formed at O is farther away from the eye than the image formed at X. Therefore, to see the car clearly at O, the eye needs to increase its focal length by adjusting the thickness of the lens, which is controlled by the ciliary muscle.
Statement 1 is incorrect because a higher focal length corresponds to a weaker lens, not a stronger one. Statement 3 is also incorrect because the ciliary muscle needs to adjust to create a thinner lens at X, not a thicker one. Statement 4 is not necessarily true based on the information given in the table, as the thickness of the ciliary muscle is not directly related to the focal length of the lens.
Other relevant points to consider in this scenario could include the distance between the person and the car, the angle at which the light enters the eye, and the size and shape of the lens and the cornea. The process of seeing an object involves a complex interaction between the eye and the brain, and there are many factors that can affect the quality and clarity of the image formed on the retina.
