What is the cause of refraction of light when it passes from one medium to another?

Solution:

Because light travels at various speeds in different media, it can change the direction of its course in another material. Or induce refraction at times. Because of the shift in light speed, as a ray of light moves from one medium to another, its direction or route (unless angle of incidence is 0 degrees) changes.
