Human Eye Colourful World Part 2 Science Ncert Cbse Class 10 Ajinkya Sir Unacademy Cbse class 10 science notes chapter 11 human eye and colourful world. human eye: working of human eye, persistence of vision, power of accommodation of human eye, defects of vision. the human eye: it is a natural optical instrument which is used to see the objects by human beings. it is like a camera which has a lens and screen system. 11.1 the human eye. the human eye is one of the most valuable and sensitive sense organs. it enables us to see the wonderful world and the colours around us. on closing the eyes, we can identify objects to some extent by their smell, taste, sound they make or by touch. To correct the myopia the person concerned should use concave lens of focal length (f) = 80 cm = 0.80 m. power of lens (p) = 1 f (m) = 1 0.80 = 100 80 = 1.25 d. ncert solutions for class 10 science human eye and colourful world part 2. 7. make a diagram to show how hypermetropia is corrected. the near point of a hypermetropic eye is 1 m. Structure of a human eye. of all the sense organs, the human eye is the most significant one as it enables us to see the beautiful, colourful world around us. the eye is spherical in shape and has a diameter of 2.3 cm on average. the internal structure of the eye includes the cornea, iris, pupil, lens, ciliary muscles, retina, nerve cells.

(i) in a myopic eye, image of distant object is formed in front of the retina. (and not on the retina) (ii) the far point (f) of a myopic eye is less than infinity. (iii) correction of myopia. Question 1: the human eye can focus objects at different distances by adjusting the focal length of the eye lens. this is due to. answer: (b) accommodation. answer 2: (d) retina. answer: (c) 25 cm. answer: (c) ciliary muscles. question 5: a person needs a lens of power −5.5 dioptres for correcting his distant vision.
