refraksiya

Refraksiya is a natural phenomenon that occurs when a wave, such as light, sound, or water waves, passes from one medium to another with a different density or composition. This change in medium causes the wave to bend or change its direction. The amount of bending depends on the angle at which the wave enters the new medium and the refractive indices of the two media.

The refractive index is a property of a material that describes how much the speed of light is reduced in that material compared to its speed in a vacuum. A higher refractive index means light travels slower in that material and bends more. For example, light bends when it passes from air into water, and again when it passes from water into glass. This is why a straw placed in a glass of water appears to be bent at the surface.

Refraksiya has many practical applications. In optics, lenses use refraksiya to focus light, which is essential for cameras, telescopes, and eyeglasses. Atmospheric refraksiya can cause celestial objects like stars to appear higher in the sky than they actually are, and it also contributes to phenomena like mirages. In acoustics, refraksiya of sound waves can affect how sound travels over distances, particularly in varying atmospheric conditions. Understanding refraksiya is fundamental to many scientific and technological fields.
