Explanation: When the light is transmitted through an object with a density different from air's such as glass, the process of refraction takes place. Light travels at different speeds in different medium because of the varying densities and thus refraction takes place.
Reflection is the the return of sound or light energy from the surface without absorbing it.
Diffraction is the phenomenon which occurs when the wave encounters an obstacle.
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. To accomplish this, each strand of existing DNA acts as a template for replication.
