Refraction of light
Refraction of light Refraction of light:-- Refraction of light is the bending of light, When ray of light travel through one medium to another medium. The speed of light is maximum in the vacuum. During refraction , the frequency of light remains same but the speed of light and wavelength changes. Refraction of light observed in many places in our daily life. When any object is immersed in the water. These object appears closer than the real position. Some natural phenomena including rainbows and mirages is also observed due to refraction of light. Some examples can be taken:-- When a coin is poured inside the filled water bucket, then the coin is appeared slightly raised above its actual position due to refraction of light. Refraction through a rectangular glass slab:-- To understand the phenomenon of the refraction of light through a glass slab, we should take a paper sheet and place a glass slab over the white paper
