A prism can help us understand the refraction and the reflection of light when it asses between 2 different mediums ( from one medium into another less refractive or from one medium into another more refractive ) and the ray of light may emerge out of the prism by refraction or by reflection and sometimes by total internal reflection ( by obeying the 2 laws of reflection and by making the angel of incidence equal to the angle of reflection ) and sometimes it may continue its path without deviation that is when the angle of incidence is equal to 0 degrees then the angle of refraction will be equal to 0 degrees this is called undeviated !It separates the wavelengths contained in a beam of light.
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
Unfortunately, the word "reflaction" is one character different from reflection and refraction. It is not possible to determine which you meant.
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
One possibility is that the medium the light is supposed to refract from is a metamaterial, an artificially created material with a negative refractive index.
The angle of incidence will equal the angle of refraction. If two medium have the same refractive index, light does not bend.
The amount of bending that a light ray experiences can be expressed in terms of the angle of refraction (more accurately, by the difference between the angle of refraction and the angle of incidence). A ray of light may approach the boundary at an angle of incidence of 45-degrees and bend towards the normal. If the medium into which it enters causes a small amount of refraction, then the angle of refraction might be a value of about 42-degrees. On the other hand if the medium into which the light enters causes a large amount of refraction, the angle of refraction might be 22-degrees. (These values are merely arbitrarily chosen values to illustrate a point.) The diagram below depicts a ray of light approaching three different boundaries at an angle of incidence of 45-degrees. The refractive medium is different in each case, causing different amounts of refraction.
angle of refraction will also decrease as according to laws of refractio sin i/sin r= constant (CONSTANT IS THE REFRACTIVE INDEX OF THE MEDIUM).

Index Of Refraction
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
Optics deals with refraction - the bending of light rays as they go from a medium of one optical density to another - as in an optical lens. Given the refractive indices of the two materials, the angle of refraction is related to the sine of the angle of incidence.
it is necessary to identify the optical density of a particular medium air for example is 1.00 and the refraction in a medium can be figured out by sinøincidence ÷ sinø refraction
1. When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
