In the human eye, the greatest amount of refraction occurs when the light passes from the air into the
a. iris
b. cornea
c. lens
d. aqueous humor
e. vitreous humor

The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.

Explanation:

The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.

When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.

the electromagnetic energy from the sun arrives in the form of visible and invisible light.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
