a laser beam is shone through a glass prism & a laser beam passes through air ->  a laser beam passes through air as it is shone through a glass prism  a prism is made of glass & glass is a kind of material ->  a glass in a glass prism is a kind of material  a glass in a glass prism is a kind of material & air is a kind of material ->  air and glass in a glass prism are kinds of materials  a laser beam passes through air as it is shone through a glass prism & air and glass in a glass prism are kinds of materials ->  the laser beam is passing from the material air to the material glass when it is shone through a glass prism  medium is made of a kind of material & refraction is when light passes from one medium to another medium ->  refraction is when light passes from one material to another material  the laser beam is passing from the material air to the material glass when it is shone through a glass prism & refraction is when light passes from one material to another material -> the laser beam will refract when it is shone through the glass prism
