It occurs when light hitting the boundary between two media comes from a denser medium?
Refraction.
Why light bends towards normal when it enters from optically rare to optically denser medium why it does not bend away from the normal?
This is because of the speed of light getting reduced as it enters into the denser medium. Think of the FRONT of the wave as it enters a more-dense medium at an angle, and its speed decreases. Vizualize it in very slow motion: -- The wave-front arrives at angle, so part of it is across the boundary and into the new medium, while part of it is still out in the old medium. -- The part of the wave-front in the new medium is traveling slower, while the part that hasn't quite reached the boundary yet is still out in the old medium and traveling faster. -- If your vizualization is running accurately, this action is causing the whole wave-front to turn, becoming more parallel with the boundary, and its direction of motion turning toward the normal.
What happens when speed of light enters a new kind of medium?
When light passes from one medium to another with a different refractive index, andnot in a direction perpendicular to the boundary between the media, its speed changes.
How light travels in a single medium in terms of speed and bending of light?
In a single homogeneous medium (electrical properties constant throughout the medium), the speed of light is constant ... although less than its speed in vacuum ... and the light does not bend. Bending (refraction) only occurs at the boundary between different media in which the speeds are different, or in a single medium whose properties change gradually (like the atmosphere).

Explain diffraction and refraction How are they similar?
They both cross the boundary from one medium to another.

Refraction.
What does light waves do when it moves from one medium to another?
A light wave can slow down or speed up when it enters another medium. Since the speed of wave motion in general depends on characteristics of the environment, you can always expect the speed of a wave to change as it moves from one medium to another. In the case of sound, it's the mechanical characteristics that matter, whereas for light and other electromagnetic waves, the determining characteristics are the electrical ones. So the speed of light changes when it enters a different medium. Now, since the product of (frequency) x (wavelength) is the wave speed, and the frequency can't change, we notice that if the speed changes, then the wavelength also changes in a new medium. Furthermore, right at the interface ... the boundary between the two media ... if the light doesn't hit the boundary exactly perpendicular to it, then we say that the light is "refracted" at the boundary, meaning that the light leaves the boundary in the new medium in a different direction compared to its direction in the previous medium.
If A pulse in a less dense medium is traveling towards the boundary with a more dense medium. Why is The speed of the transmitted pulse will be less than the speed of the incident pulse?
The speed is Inversely dependent on the density of the medium, s=c/n(density)

What type of plate boundary are most earthquakes found at?
All three type of Earthquakes (Shallow-seated, Medium-seated and Deep-seated) occur only at the Convergent plate boundary. At divergent plate boundary we find mostly Shallow-seated Earthquakes only.
When a wave bends as it passes from one medium to another what occurs?
Refraction is the change in direction of a wave when it reaches a boundary between two media due to traveling at different speeds in each medium.
A pulse reaches the boundary of a medium in which the speed of the pulse becomes higher. Is the reflection of the pulse the same as for the incident pulse or is it inverted?
same
What happens to to light waves as they pass through water?
if the light rays are coming from air, they will be refracted at the water boundary towards the normal. refraction occurs because the light rays change speed at the boundary as they travel faster in a less dense medium (air) than they do in a more dense medium (water). hope this helps. alert me if it doesn't :)
What happens when speed of light enters a new kind of medium?
When light passes from one medium to another with a different refractive index, andnot in a direction perpendicular to the boundary between the media, its speed changes.
What are the conditions for total internal reflection to occur?
It occurs when light traveling from one medium to another is completely reflected at the boundary between the two materials. The angle of incidence must be over a certain value (depending on the optical properties of the materials at the boundary).
What two factors affect how much light is refracted?
The speed of light . ( but it's mostly ignored , since speed of light is constant in air " 3.0×108" )The Refractive Index of the medium the light is getting into .The angle of incidence to the boundary of the Medium.
