Question

why does the refraction light ray does not takes place from the surface separating the two different mediums having same refractive index???​

Answer 1

Answer:

refraction happens when light enters a medium where its speed is different or when it passes from a fast medium to a slow medium. If a ray of light is incident normally to the surfaces, then deviating from the normal will always increase the time of travel according to the snell’s law.
