Answer:
Physics, Quantum Mechanics
Explanation:
Light is a stream of photons with no weight. If you want to dig deeper in this mysterious phenomena, you should study physics and quantum mechanics. Physics takes up things like the theory of relativity, which can be useful in studying spacetime and how light travels through it, and quantum mechanics, being the study of matter in an atomic level, should help you get an understanding on how photons of light travel and why they behave so strangely.
Answer:
Following is the program in C language :
#include <stdio.h> // header file
#define n 5 // macro
int main() main function
{
int a[n],k1; // variable and array declaration
printf("Enter the element:\n");
for(k1=0;k1<n;++k1) //iterating the loop
{
scanf("%d",&a[k1]);//Read the values by user
}
printf("Output in Reverse Order:\n");
for(k1=n-1;k1>=0;--k1)//iterating the loop
{
printf(" %d ",a[k1]); //Display the values
}
return 0;
}
Output:
Enter the element:
4
3
45
67
89
Output in Reverse Order: 89 67 45 3 4
Explanation:
Following is the description of the program
- Define a macro "n" with value 5 after the header file.
- Declared an array "a" and defined the size of that array by macro i.e "n".
- Read the value by the user by using scanf statement in the array "a"
- Finally In the last for loop display the values of array "a" by space.
Answer: Virtualization
Explanation: Virtualization is the term that describes about creation of something than its actual version. In computer field , virtualization can happen in the storage devices, server elements,network components , operating systems etc.
The mechanism of virtualization helps in a creating a framework in which the resources is divided into multiple units so that more execution and processing can be done in operating system environment. So, the data center has used the virtualization trend for the separate web servers
