It will be refracted accordingly, based on Snell's law. In this case, the angle of incidence is smaller than the angle of refraction, and as it is traveling from a more dense to a less dense medium, it may undergo total internal reflection, provided that the angle of incidence is greater than the critical angle.
The light ray bends when it enters a medium with different density. It either bends towards or away from the normal depending on whether the medium is more dense or less dense.
It slows and bends.
a light ray is refracted when it passes from one medium to another at an angle and its speed changes. at the interface , it is bent in one direction if the material enters in denser and in the other direction if less dense.
Medium A is the more optically dense medium. As when the light enters B its speed increases taking it toward the normal.

If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
The light bends when it passes from one medium to another. But only if it approaches the interface at an angle. In such a case it will still travel slower, but there will be no apparent bending.
It slows and bends.
-- Its speed becomes less in the denser medium. -- Its wavelength becomes greater in the denser medium. -- If its direction is not perpendicular to the boundary between the media, then its path in the denser medium is closer to the perpendicular. (This is 'refraction'.)

The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
light enters the fiber optic wire at what is known as a critical angle. As the light bounces off the inside of the wire it does so at or above the critical angle and thus it cannot escape the fiber optic wire. the reason for this phenomena is because the medium of the wire is more dense then that of the medium outside the wire.
The answer depends on what on earth you mean by the "dirtier" of a wave.
