Answer 1

Answer:

the process by which green plants turn carbon dioxide and water into food using energy from sunlightthe process by which green plants turn carbon dioxide and water into food using energy from sunlight

Answer 2

Answer:

The ratio of velocities of a light ray in the air to the given medium is a refractive index. Thus, the relation between the critical angle and refractive index can be established as the Critical angle is inversely proportional to the refractive index.
