Light with a wavelength of 420 nm shines on a metal surface, which emits electrons. The stopping potential is measured to be 0.660 V. a. What is the maximum speed of emitted electrons?b. Calculate the work function. c. Identify the metal.

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
