WebThis bending is called refraction. The amount, or degree, of refraction is related to the difference between the speeds of light in the two materials of different densities—the greater the difference in densities, the more the speed changes, and the greater the bend.

WebThe bending is called refraction. It happens because light travels at different speeds in different materials. If light rays travel through air and enter a more dense material, such as water, they slow down and bend into the more dense material. Light rays moving into a less dense material, such as from water to air, speed up and bend outwards. WebRefraction through a prism Refractive index depends on the frequency or colour of light. Light of higher frequency has a greater refractive index than lower frequency light. This explains why a...

WebReflection is when light hits the surface of an object and then that light travels to our eyes so we can see. The reflected light from objects is absorbed by our eyes to form images of the world around us. Smooth surfaces such as mirrors, water and some metals reflect the most light which is why they appear shiny.
