Refraction of light in the eye occurs at: (a) the lens only (b) the cornea only (c) both the cornea and the lens (d) the pupil
(c) both the cornea and the lens
(c) both the cornea and the lens
(a)The cornea is the portion of the eye’s front that allows light to enter.(b) Iris: The iris regulates how much light enters the eye.(c) Pupil: The pupil controls how much light enters the eye.(d) Ciliary muscles: These help the eye lens to contract and relax.(e) The eye lens aids in concentrating light on the retina.(f) …
(a) (i) In dim light, pupil becomes large (ii) In bright light, pupil becomes small (b) ( i) Cones (ii) Rods (iii) Cones
(a) The convex eye lens differs from a regular convex lens in that the ciliary images govern its focal length, whereas a regular convex lens’s focal length is maintained by adjusting the glass’s focal length.(b) Retina, cornea, pupil, and eye lens.
The retina of the eye is made up of rod and cone cells. Rods are cells with a rod-like structure that are sensitive to low light. Cones are formed like cones and are sensitive to intense light. Due to the presence of fewer rod cells than owls, humans have less effective night vision than owls.
(a) The retina contains both of the types of light-sensitive cells.(b) Rods and cones are the names of these cells.(c) While cones are sensitive to bright light, rods are sensitive to low light.
The ciliary muscles are used to help the eye concentrate on distant things. The suspensory ligaments are pulled and connected to the eye lens as the ciliary muscles completely relax.
