(a) Diagram showing the field of view corresponding to the following images. (b, c) Trajectory of drops for two different heights of the slide: h₁ = 2.6 cm and h₂ = 0.7 cm. We observed a smaller impact angle for h₂ (10 ± 2°) than for h₁ (25 ± 2°). Both images are obtained from successive frames (300 fps) layered in a single one to reconstruct the full trajectory.
