Answer:

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.[1] Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Explanation:

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Types of Refractive Error

◆Myopia. Myopia, also called nearsightedness, is the inability to see distant objects clearly. ...

◆Hyperopia. Hyperopia, also called farsightedness, occurs when distant objects are easier to see clearly than nearby objects. ...

◆Astigmatism. Astigmatism is blurred vision caused by an unusually shaped cornea, Presbyopia.

The two laws followed by a beam of light traversing through two media are:

●The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.

●The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.

The four most common refractive errors are: myopia (nearsightedness): difficulty in seeing distant objects clearly; hyperopia (farsightedness): difficulty in seeing close objects clearly; astigmatism: distorted vision resulting from an irregularly curved cornea, the clear covering of the eyeball.
