The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. The angle of incidence is equal to the angle of reflection because the light ray selects the shortest path to reach the destination. This behavior of light is known as Fermat’s principle.

The angle of incidence is also 55 degrees because it is reflected
A prism can help us understand the refraction and the reflection of light when it asses between 2 different mediums ( from one medium into another less refractive or from one medium into another more refractive ) and the ray of light may emerge out of the prism by refraction or by reflection and sometimes by total internal reflection ( by obeying the 2 laws of reflection and by making the angel of incidence equal to the angle of reflection ) and sometimes it may continue its path without deviation that is when the angle of incidence is equal to 0 degrees then the angle of refraction will be equal to 0 degrees this is called undeviated !It separates the wavelengths contained in a beam of light.
The definition of critical angle is the angle of incidence that refraction can still occur.
Yes; if angle of incidence is zero angle of refraction is zero regardless of index: sin theta r = (n1/n2) sin theta i
VIERRA! The angle of incidence.
