### Program files

There are actually two files in this Set. The first of these programs is 'find.cpp'. find was built as a program to calculate the length of A.C. Sonometer wire which gives the correct reading, which we are looking for.

#### Header files

#include <iostream> #include <math.h>

##### Set namespace

using namespace std;

#### Define functions

###### calc():

This is a function which will solve this equation( ) with the variables provided.

float calc(float t,float u,float l){ return sqrt(t)/(2*l*sqrt(u)); }

###### ten():

This function will multiply the value of weight by the constant of acelleration due to gravity.

float ten(float x){ return x*0.0098; }

###### com():

This function returns the mean of the two length input.

float com(float x1, float x2){ return(x1+x2)/200; }

###### main():

Here this function will run through at the beginning and end of the program.

int main() { int w; float n,t,u,l1,l2,l; cout<<"Calculate Frequency of AC from lengths on Sonometer!!\n"; cout<<"What are the lengths?(cm)\nl.1:"; cin>>l1; cout<<"l.2:"; cin>>l2; l=com(l1,l2); cout<<"Mean length = "<< l <<" What is the value of weights(g)? "; cin>>w; t= ten(w); cout<<"Tension = "<< t; cout<<" Kgm/s\nWhat is the value of linear density of wire U(g/m)?\n"; cin>>u; n=calc(t,u,l); cout<<"\nTherefore frequency of AC is "<< n <<" Hz\n"; return 0; }
