Refraction is the change in the direction of a wave passing from one medium to another.” Refraction of light is one of the most commonly observed phenomena, but other waves like sound waves and water waves also experience refraction.
Refraction is the bending of light or other waves when they pass from one medium to another with different speeds. For example, when a pen is partially submerged in water, it appears bent because the light from the pen changes direction as it travels from water to air. Refraction is also what makes lenses, prisms, rainbows, and our eyes work. Refraction follows Snell’s law, which says that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the refractive indices of the two media. The refractive index is a measure of how much a medium slows down light. The higher the refractive index, the slower the light and the more it bends. Refraction depends on the wavelength of light, which means that different colors of light bend differently. This is called dispersion and causes white light to split into a spectrum of colors when it passes through a prism or a raindrop.
Some examples of refraction in everyday life are:
A magnifying glass uses a convex lens to refract light and make objects appear larger.
A straw in a glass of water looks broken or displaced because of the change in the direction of light at the water surface.
A mirage is an optical illusion caused by the refraction of light in the air when there is a temperature gradient. The light bends away from the normal and creates the appearance of a distant object or water.
The human eye has a lens that refracts light and focuses it on the retina, where the image is formed. The eye can adjust the shape of the lens to focus on objects at different distances.
