This is total internal reflection where the angle of refraction is 90 degrees and its incident angle would be the critical angle(angle of incident for which the angle of refraction is 90)....
This hapens when the angle of incidence is in a medium more dense than the angle of refraction's medium

Why ray of light travelling along the normal does not refract?
A ray of light traveling along the normal does not refract because it is already traveling along the normal line, which is the interface between two different mediums and the direction of the refracted light. Since it is already following the normal, there is no change in direction and, therefore, no refraction.
Can a wave refraction when it enters a medium along the normal line?
No, a wave does not refract when it enters a medium along the normal line. Refraction occurs when a wave enters a new medium at an angle, causing it to change speed and change direction. If the wave enters the medium along the normal line, it will continue in the same direction with no refraction.
Does a car traveling along a curved path at constant speed have a constant momentum?
Yes, a car traveling along a curved path at constant speed does not have constant velocity since velocity is a vector quantity that includes direction. However, the magnitude of the car's momentum (which is the product of mass and velocity) can remain constant if there are no external forces acting on it.
What is the rate of change of an object's position over a period of time without information about the direction in which the object is traveling?
The rate of change of an object's position over time without direction information is its speed. Speed is a scalar quantity that represents how fast an object is moving along its path, regardless of the direction of motion.
An object traveling in a circle is accerlerating because it is constantly changing?
An object traveling in a circle is accelerating because its direction is constantly changing as it moves along the circular path. This change in direction, even if the speed remains constant, results in an acceleration towards the center of the circle, known as centripetal acceleration.

What are the 2 conditions when the direction does not change on refraction?
-- Light approaches the boundary between any two media along the normal direction. -- Light approaches the boundary at any angle and the indexes of refraction of both media are equal.

If a ball is rolling and ramp you apply more force in the direction it is traveling what will happen?
If you apply more force in the direction the ball is already traveling, it will accelerate and its speed will increase. The additional force will cause the ball to roll faster along the ramp.
How can a car be travelling at a constant speed yet be be accelerating?
A car can be traveling at a constant speed but still be accelerating if its direction changes. Acceleration is a vector quantity that includes both speed and direction. So, even if the car maintains a constant speed along a curved path, it is still accelerating due to the change in its direction.
Which velocity component changes along the path?
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
What two things can change in velocity do?
Two things that can change in velocity are speed and direction. Speed refers to the rate at which an object is moving, while direction indicates the path along which the object is moving. Both speed and direction can change independently to result in a change in velocity.
Can a particle moving with uniform speed along a curved path have acceleration?
Yes, a particle moving with uniform speed along a curved path can have acceleration because acceleration is the rate of change of velocity, which includes changes in direction even if speed remains constant. In this case, the acceleration would be due to the change in velocity direction as the particle moves along the curved path.
What simple machine does not change the direction of force?
The simple machine that does not change the direction of force is the inclined plane. It allows you to exert a force in one direction (up or down the incline) to move an object along the ramp without changing the direction of the force.
