Name the bending of light, if the ray of light passes diagonally from one medium to another. 

If the ray of light passes diagonally from one medium to another, also the bending of light is known as refraction. Whereas, reflection means change in direction of light, at an interface, between two different mediums, similar that the light returns into the medium from where it had began. dissipation is the property by which spreading of light takes place according to its color, as it passes through an object. Dispersion is the bending of a ray of light, down from a straight line by an angle called angle of dispersion.
