C. absorption
D. reflection
The correct answer is (b) Refraction
When a beam of light is passed from one medium to another medium then the beam of light bends when it passes from one medium to other, this phenomenon is called as Refraction. This change can be determined by measuring the change in the wave speed and the initial direction of wave relative to the direction of the change in speed. Example: when a beam of light is passed through a prism, when a laser light is passed through a ice cube.

Condensation is a process in which the gaseous form of water is converted into liquid. It is very important for the water cycle. This results in the formation of the clouds, fog and dew. For the occurrence of condensation, the air must be saturated. Saturation occurs most commonly when the warm air in the atmosphere cools down to it's dew point. The condensed water vapors and some of the particular matter forms the clouds.
