a = 0.04; // Slit width, cm
x = 0.5; // Half width of central maximum, cm
f = 300; // Focal length of the lens, cm
// As x = lambda*f/a, solving for lambda
lambda = a*x/f; // Wavelength of light used in Fraunhoffer diffraction due to single slit, cm
printf("\nThe wavelength of light used in Fraunhoffer diffraction due to a single slit = %4d angstrom", lambda/1e-008);
// Result
// The wavelength of light used in Fraunhoffer diffraction due to a single slit = 6666 angstrom
