Answer» velocity of light is more is vacuum and less in water. the velocity changes with refractive index of the MATERIAL thro which light passes.An inverted IMAGE is formed in a pinhole camera because the light rays COMING from the top and bottom of the OBJECT intersect at the pinhole. EXPLANATION:
