(a) If the cornea were simply thin lens then power will be 43 diopters.
(b) This is a concave lens
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Despite injury or disease, the cornea can still repair itself quickly. However, there are situations where damage is too severe for the cornea to heal on its own – such as with a deep injury to the cornea. The following symptoms may indicate that the cornea has sustained a substantial infection, injury or disease: Blurred vision Pain Redness.
Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 diopters.
There are two types of lenses: converging and diverging and here if the cornea was simply thin then the diverging or concave lens is used in the eyes which is thin in the center than their edges.

Answer:
can you explain more or..,.
Explanation:
Tornadoes are more common in the united states than in the other countries. united states received a total of 1,200 tornadoes annually, four times the amount seen in europe. most tornadoes in the united states occur east of the rocky mountains. the great plains, the midwest, the mississippi valley and the southern united states, are all areas that are vulnerable to tornadoes.
Using Planck's equation,
E = nhc / λ
Also, Power = Energy / time
E = 20 x 10⁻³ x 60 x 60
E = 108 J
108 = (2.29 x 10²⁰ x 6.63 x 10⁻³⁴ x 3 x 10⁸) / λ
λ = 4.22 x 10⁻⁷ m
