//Given data
n=0.6; // Quantum efficiency
e=1.602*10^-19; // Charge of electron
lambda=0.9*10^-6; // Wavelength
h=6.626*10^-34; // Planck constant
c=3*10^8; // Velocity of light
I=2*10^-6; // Photocurrent
// a)Responsivity
R= (n*e*lambda)/(h*c);
// b)Incident power
P=I/R;
P=P*10^6;
//Displaying results in the command window
printf("\n Responsivity(in A/W) = %0.3f ",R);
printf("\n Incident power (in microwatt) = %0.3f ",P);
// The answers vary due to round off error
