ANSWER
If a ray of light falls normally onto a glass slab, the three optical phenomenon all happen.
A part of the ray is:
TRANSMITTED through the slab. This part of the light travels slower than it would in a vacuum, as it is now inside glass. Its wavelength would have also changed
REFLECTED at the surface, and retraces its incident path
ABSORBED by the glass, and the energy is dissipated by heating.
While most of the answers say refraction does not happen, refraction does actually happen. It is just that the ray refracts in such a way that it doesn’t deviate from the path it was initially following, i.e., there is no “bending” of light.
1.
a concave mirror gives the dentist a magnified reflection of the mouth of patient
2.
the reflection of light in glass prism is different from glass slab this is because in glass prism the incident ray of light Is not parallel to emergent ray of light when a ray of light get enters in glass prism it gets deviated two times
