plz answer me fast tomorrow my is their​

Answer 1

Answer:

mate for now I can only answer you the 11th question..

the answer is flattened

Answer 2

11. When the ciliary muscles are relaxed, the eye lens becomes thin

12. The far point of the eye is the maximum distance to which the eye can see the objects clearly.

13. The human eye can focus objects at different distances by adjusting the focal length of the eye lens This is called the accommodation

14. A normal eye is unable to clearly see the objects placed closer than 25 cm because the

ciliary muscles of

eyes are unable to contract beyond a certain limit.

15. Red color has the longest wavelength in the visible range of light.

16. The phenomenon of spreading out or diffusion of a beam of radiation when it is incident on some

matter surface is known as scattering of light.

17. The intensity of scattered light varies inversely to the fourth power of the wavelength of incident light .

18.Greater the wavelength of the light, Less

is the scattering by the atmosphere.

19. The phenomena of light are involved in the formation of a rainbow are reflection, refraction and dispersion.

21. The first person to obtain the spectrum of sunlight is Issac Newton

22. A person needs a lens of power -5.5 dioptre for correcting his distant vision. The focal length of the lens required for correcting this vision is -1/5.5

23. A person needs a lens of power +1.5 dioptre for correcting his near vision. The focal length of thelens required for correcting this vision of 1/1.5

24. A concave lens of power -1.25 D is required by the person suffering from myopia to correct his defect.
