A wave that enters a new medium will experience interference. It is the interference that causes the observed phenomenon we observe when a wave enters a new medium.
If a wave enters an environment in which it changes speed, the part that enters first appears to lag-behind or lead-in-front the original. That light refracts in this way strongly suggests that it has wave properties and that its speed has to change in moving between air, glass, and water fo example.
The slight difference in the speed of light
Change of speed in the new medium. A wave striking at an angle has its leading edge slowed or speeded up, just as in light refraction in glass.
When a ray of light travels from one transparent medium into another medium, it bends while crossing the interface, separating the two media. This phenomenon is called refraction.
Q: How do you think increasing a medium's index of refraction might affect the angle of refraction?
Reflection is a change of the angle of light without a change of medium. Refraction is a change of the angle of light with a change of medium.
yes, if the pencil is in water, its refraction because when a wave enters a new medium, the waves speed changes and moves in a different angle. that's why a pencil looks broken in water
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
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.
how can the path of a light ray be affected once it enters a nonzero angle with a greater index of refraction

Definitely possible asmedium 2 is found rarer compared to medium 1

Since the angle of incidence is 0, there is no chance of refraction and so the angle of refraction too becomes 0.
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.
