A dichromatic light of wavelength 5600 A ∘ and 6300 A ∘ pass through a prism of crown glass. Then:

deviation for wavelength 5600 A ∘ is greater than deviation for wavelength 6300 A ∘

deviation for both wavelengths is same

both will emerge without deviation

deviation for wavelength 6300 A ∘ is greater than deviation for wavelength 5600 A ∘ .

Write the function of ciliary muscles of human eye.

The ciliary muscle is an intrinsic eye muscle that forms a ring of smooth muscle in the central layer of the eye (vascular layer). It regulates the flow of aqueous humour into Schlemm's canal and governs accommodation for viewing objects at different distances. The zonules are relaxed or tightened by this muscle, allowing the lens to change shape for focusing. The zonules are fibres that keep the lens in place while allowing it to change shape during accommodation.

Write the function of crystalline lens of human eye.

The crystalline lens, also known as the lens of the eye, is an important part of the anatomy of the eye that allows the eye to focus on objects at different distances. It is situated in front of the vitreous body, behind the iris. It's also bendable, allowing it to change shape and bend light to appropriately focus on the retina.

Write the function of cornea of human eye.

Cornea is a thin membrane that surrounds the eyeball and protects it. It works like a lens, refracting the light that enters the eye. The cornea, along with the sclera, acts as a barrier against dirt, bacteria, and other particles that could harm the sensitive components of the eye. The cornea also filters out some UV light from the sun.
