The cornea is responsible of refraction light 1/3 in eye.
<h3>What is the function of the cornea?</h3>
In addition to the protective function, it plays a fundamental role in the formation of vision. Transparent, it works like a lens over the iris, focusing light from the pupil towards the retina.
Normally, the cornea and lens deflect (refract) incoming light rays, focusing them on the retina. The shape of the cornea is fixed, but the lens changes shape to focus on objects at different distances from the eye.

Answer: Copper and oxygen
Explanation:
Copper and oxygen shares the ionic bond. As we know that ionic bond is the most strongest bond. Here is the order:
Hydrogen bond< Metallic bond< Ionic bond.
That means order in terms of increasing bond strength is :
Hydrogen and hydrogen< Copper and copper< Copper and oxygen.
The question is incomplete. Here is the complete question.
A floating ice block is pushed through a displacement vector d = (15m)i - (12m)j along a straight embankment by rushing water, which exerts a force vector F = (210N)i - (150N)j on the block. How much work does the force do on the block during displacement?
Answer: W = 4950J
Explanation: <u>Work</u> (W), in physics, is done when a force acts on an object that has a displacement form a place to another:
W = F · d
As the formula shows, Work is a scalar product, i.e, it results in a number, so, Work only has magnitude.
Force and displacement for the ice block are in 2 dimensions, then work will be:
W = (210)i - (150)j · (15)i - (12)j
W = (210*15) + (150*12)
W = 3150 + 1800
W = 4950J
During the displacement, the ice block has a work of 4950J
Answer:
1.87 s
Explanation:
d = distance traveled by the water wave = 64 m
t = time taken to travel the distance = 14 s
= speed of water wave
Speed of water wave is given as
= 4.6 m/s
= wavelength of the wave = 859 cm = 8.59 m
T = period of the wave
period of the wave is given as
T = 1.87 s
As the distance between the two slits is <span>decreased, the distance between light bands in the pattern on the screen will increase. The correct option among all the options that are given in the question is the second option or the penultimate option. I hope that this is the answer that has actually helped you.</span>
