Want this question answered?
They are refracted, and the new angle of travel appears as an increase to the initial angle of incidence.
The light rays will refract towards the normal of the medium and emerge out at the same angle.
when light rays enter a new medium in a new angle it may speed up or speed down
Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.
It is called the central angle. Hope that helped!

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.
Type your answer here... it is called as the refraction.
For refraction to occur in a wave, the wave must enter a new medium at an angle.
That's called "refraction".
You enter at a 45 degree angle
