    In a single slit diffraction experiment, for a wavelength of light λ\lambda, half-angular width of the principal maxima is θ\theta. Also for wavelength of light pλp\lambda, the half angular width of the principal maxima is qθq\theta. The ratio of the half-angular widths of the first secondary maxima in the first case to second case will be

    In a single slit diffraction experiment, for wavelength 'λ\lambda', half angular width of the principal maxima is 'θ\theta'. Also for wavelength of light 'pλp\lambda', the half angular width of the principal maxima is 'qθq\theta'. The ratio of the half angular widths of the first secondary maxima in the first case to second case will be
