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.
Refraction
refraction
When a ray of light strikes an obstacle it changes its path this is called reflection of light whereas the bending of light ray while traveling from one medium to other is called refraction.
The angle of refraction is the angle between the refracted ray and the normal (a perpindicular line to the tangent and the plane of the surface). A ray that enters at the normal angle leaves at the normal angle; there is no angle between the ray and the normal, so it is 0o.

refraction
Refraction is the bending of light when it passes from one medium to another medium (like from air to glass). The basis for refraction is the speed of light is slightly different in the two mediums. Diffraction is the bending of light that occurs around a sharp edge (like light passing thru a slit). The basis for diffraction is the spreading out of the wave as it passes by the sharp edge.
the difference is transmission occur in same medium,but refraction occurs whn 2 medias are there,its actually bending of light at interface of 2 medias
Hey there ^^ ... it is actually Snell's Law, has to do with refraction.First of all refractions is the bending of light as it passes from one transparent medium to the next...Snell's law is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water and glass.ORsnell's law is the physical law that defines the relationship between the angle of incidence and the angle of refraction

That depends on the substances where the refraction occurs. The relationship between the angles, and the index of refraction of both materials, is given by Snell's Law.
The amount of bending certainly CHANGES depending on the frequency, but there is no simple relationship between frequency (or wavelength) on the one hand, and the index of refraction (and therefore the amount of bending) on the other. If by "infer" you mean to calculate this depending on the properties of the material, I don't think there is an obvious way to do this.
The bending effect called refraction happens when waves cross the boundary between two different media. However, there will be no bending if (a) the left and right sides of the waves encounter the boundary simultaneously or (b) the speed of the waves is the same in both media. This is because bending only occurs when one side of the wave overtakes, i.e. advances relative to the other.
That is called "refraction".
