In a single slit diffraction experiment, inciden
grn y(ma) f;t)t light passes through an aperture and a diffraction pattern is observed on a distant s
)afmty( g; nr)creen. $X$ is a point on the screen between the second-order minimum and the first-order minimum. $Y$ is a point at the centre of the principal maximum.
Which one of the following could be the ratio of the intensity of light on $X$ to the intensity of light on $Y$?
