I saw this video where someone says that electromagnetic wave is a chain reaction of electric and magnetic fields creating each other so the chain of wave moves forward.
I wonder where the photon is in this explanation. What is the relation between electromagnetic wave and photon?
If electromagnetic wave is what happens calls radiation in the first place and says photon is smallest part of electromagnetic wave, then what's this calling it radiation in the first place?
Is it correct to think of photons as standing waves or as moving packets of energy? Which uses both terms interchangeably, but in different contexts, so it makes things even more confusing.

Given a number n, print n-th Fibonacci Number using a recursive method.

Example:
n = 10
return 55  // return Fibonacci_number(10)

Recursive Solution:

To calculate the Fibonacci number, we have an iterative method as well as a recursive method.

1. Fibonacci iterative method: We start with an initial value for first and second numbers in the sequence and using a third variable we update the first and second numbers to calculate next value in sequence.
2. Fibonacci recursive method: We define a function to calculate
