Why the light wave entering the second medium show no change in direction?

I can't see the setup of your experiment, so there's no way I could know
why that happened in your case. But I can think of two possibilities where
that would happen:
1). The light wave would not change direction if the refractive index of both media
is the same number, regardless of what direction it approaches the boundary from.
2). The light wave would not change direction if it approaches perpendicular to the
boundary, regardless of the refractive index of either medium.

What is the name of when light rays travel form one medium to another?
Refraction is when they change direction slightly when entering the second medium, e.g. flashlight shining down towards water surface
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
Can a second class pulley change the direction of the effort force?
yes
When you have a bird going 10 meters per second and its direction is northeast what is the acceleration?
As long as the speed doesn't change and the direction doesn't change, its acceleration is zero.
How does the newton's second law of motion apply on a bicycle?
Newtons second law applies two bicycling because when your bike is going down hill, and you don't have to petal, your bike will not change direction unless you physically change the direction.
Why does a satellite doesn't charge it's direction quickly?
Any quick change of direction requires a powerful force (according to Newton's Second Law).
How does a wave change direction when it bounces off a surface?
the answer is simple its the angle of incidence always equals the angle of reflection
What is a rarer medium?
If the light travels faster in the second medium, then this medium is called the rarer medium.
What does baud rate measure?
The baud rate measures the number of times the transmission medium can change its state in one second, which is the number of discrete signals in a given second. Baud rate is the speed of transmission when using modems over telephone lines.
It takes force to change what?
Either mass or acceleration according to Newton's second law of motion and in general ,direction.
Is y equals 2x-2 and y equals 2 parallel?
No. The slope of the first is 2 - ie a change in the horizontal direction results in double the change in the vertical direction. The second line is horizontal (slope = 0).
Who is the second leader of One Direction?
There is no 'leader' or 'second leader' in One Direction.
