Why a ray of light entering the second medium perpendicular through the surface of separations shows no change of direction?

when incident is perpendicular to the plane of separation of two media then angle of incident is equal to zero so
sin I =sin 0=0
by snell's law we get n=0 or refractive index is zero so ray goes straight

What describes the motion of the media for a surface wave?
The motion is parallel to wave direction The motion is both parallel and perpendicular to wave direction. The motion is perpendicular to wave direction.
What is a transvers wave?
If the simple harmonic vibrations are in perpendicular direction to the direction of propagation of the wave then it is said to be transverse. Example: waves on the surface of water.
What is the meaning of the normal force perpendicular to the surface of the contact?
In this context ... referring to directions at a surface ... the word "normal" doesn't mean 'usual' or 'typical'. It means the direction perpendicular to the surface. Knowing this strange (abnormal) use of the word should clear up the confusion.
Why are waves on the surface of the water transverse?
Transverse waves oscillate perpendicular to the direction of energy propagation. Think of one wave by itself. Which direction is it propagating? Some direction parallel to the surface of the water. Now think of one particular piece of water that the wave passes through. It's motion goes upwards and downwards, which is perpendicular from the surface of the water, therefore transverse. Waves oscillating parallel to the direction of energy propagation are called longitudinal.
What is the difference between longitual waves and transverse waves?
longitudinal waves travel in the direction parallel to the Surface, which are P waves, and transverse waves travel in the direction perpendicular to the surface, which causes destructive earthquakes. Which are S waves.

Why a vertical datum is alevel surface not a horizontal surface?
because the datum surface is perpendicular tothe direction of gravity at any point on it.but the horizontal surface is perpendicular to vertical at one point on it :D
What is the angle formed by the line perpendicular to a surface and the direction in which a reflected ray moves?
0 degrees

What is a line perpendicular to a surface called?
The line perpendicular to a surface at a point is called the normal
What is a normal ray in a diagram of reflection of light?
"Normal" means perpendicular to the boundary or reflecting surfaceat the point where the ray hits it.
What is the change in direction of waves when the waves travel from air to glass?
The waves are refracted towards the normal (ie towards the line perpendicular to the surface).
What is angular value of normal in refractive index?
The "normal" to a surface or a boundary is the direction perpendicular to it. Within the scope of this discussion, it has nothing to do with refractive index.
