Question

The human eye and the colourful world.....plzz give me some notes....this for class 10.....​

Answer 1

Answer:

⊕ The ability of the eye to focus on both near and distant objects, by adjusting its  focal length, is called the accommodation of the eye.

⊕ The smallest distance, at which the eye can see objects clearly without strain, is  called the near point of the eye or the least distance of distinct vision. For a young  adult with normal vision, it is about 25 cm

⊕ The common refractive defects of vision include myopia, hypermetropia and  presbyopia.

⊕ Myopia (short-sightedness – the image of distant objects is focussed  before the retina) is corrected by using a concave lens of suitable power.

⊕ Hypermetropia (far-sightedness – the image of nearby objects is focussed beyond  the retina) is corrected by using a convex lens of suitable power. The eye loses its  power of accommodation at old age.

⊕ The splitting of white light into its component colours is called dispersion.

⊕ Scattering of light causes the blue colour of sky and the reddening of the Sun at  sunrise and sunset.
