Is reflection different from refraction?
Reflection is the return of lightwave after it hits a smooth and polished surface. The ray that bounces back is called the reflected ray. With respect to the normal, the angle of incidence is equal to the angle of reflection. There are two types of reflection.
1) Regular reflection
2) Diffused reflection.
whereas Refraction is the bending of light when traveling from one medium to another medium. The bending of light is caused by the differences between the densities of the two mediums. An example of refraction is the bending of the sun's rays as they enter raindrops, forming a rainbow.
Differences between reflection and refraction are:
| Reflection | Refraction | |
| 1. | Here light ray bounces back after it hits a surface. | Here a light ray bends after traveling from one medium to another medium. |
| 2. | It is of two types. 1) Regular reflection 2) Diffused reflection | It is of a single type. |
| 3. | No change in medium is necessary to change the direction of the light ray. | Here a medium change is necessary to change the direction of light |
| 4. | Here the angle of incidence and the angle of reflection are the same. | Here the angle of incidence and the angle of reflection are different. |
| 5. | Here the medium of propagation is the same | Here the medium of propagation is different. |
