A bichromatic light having wavelength gamma_1 and gamma_2 falls normally on a single slit and produces a diffraction pattern. It is found that the first diffraction minimum for gamma_1 is at 30^(@) and second diffraction minimum for gamma_2 is at 45^(@) from the central maximum. If gamma_1 is 5000xx10^(-8) cm, then the value of gamma_2 is close to:
