Question and answer
Q: what is refraction?
A: n= sin i/sin r n = refractive index i = angle of incidence r = angle of refraction or refractive index =velocity of light /phase velocity phase velocity =lambda/time For the refractive index of a certain substance: n=velocity of light in a [ vacuum/velocity of light in the substance ]

User: is refraction when light bends?

Weegy: The speed of the light ray changes upon changing mediums. In almost every case the direction of the light ray changes also. The medium the ray travels through effects how much the light is refracted.

Refraction : the change of direction of a ray of light, sound, heat, or the like, in passing obliquely from one medium into another in which its wave velocity is different.
