Question

Achievement and failure of 12th five year plan on education

Answer 1

Explanation:

At the point of incident ray, refracted beam and the typical to the air-glass interface, all lie in the plane of paper.  

Inside experimental limits, the angle of emergence and angle of incident  are equivalent.  

The rising beam is parallel to the incident beam.  

Emergence beam is horizontally dislodged.  

At the point when the light beam goes from optically rarer medium (air) to optically denser medium (glass), the edge of refraction is not exactly the edge of frequency.  

The refracted edge at the air-glass interface and the occurrence point at the glass-air interface are observed to be equivalent.
