The yellow lines show how light is bent as it passes through a magnifying glass. This is an example of:
-
Absorption
No. The glass is clear, telling us that very little of the light is being absorbed. Absorption does not bend the light. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the rays of light go in many different directions. -
Refraction
Yes! Refraction bends light as it moves from one substance to another. As the light passes through the curved lens of the magnifying glass its path is changed, bending the rays towards the focal point. -
Reflection
No. While some light is reflected from the glass, it is not responsible for the bending of the light.
