A single slit forms a diffraction pattern, with the first minimum at an angle of 40 ° from central maximum. Monochromatic light of 630 nm wavelength is used. the same slit, illuminated by new monochromatic light source, produces a diffraction pattern with the second minimum at a 60 ° angle from the central maximum. what is the wavelength of this new light ?
