angle = %pi/2 // scattering angle of photon
h = 6.624e-34 // plank's constant
v = 2e6 // speed of particle
e = 1.6e-19 // charge on electron
m = 1e-3 // mass of particle in kg

printf("\n Here the de Broglie wavelength is too small to be detected. This wavelength is far smaller than the wavelength of X ray.\n Hence diffraction experiment with such a stream of particle will not be successful.")
