How is refraction different from reflection? a. refraction occurs only within the same medium b. the light travels at the same speed as before it was c. the angle of refraction is measured from the flat surface rather than from the normal d. the angle of refraction is not necessarily equal to the angle of incidence

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
