AIRR (Aerial Imaging by Retro-Reflection) has been proposed as a method to form an aerial image in the air where nothing exists. In a previous study, the image formation position and size of an aquatic image formed by AIRR were reported. In this study, we will confirm the possibility that the spread of a point image formed in water from a point on a light source set in the air changes depending on the divergence angle of the light from the light source.
