1.

Pls tell me the ans.

Answer»

l draw the conclusion that ANGLE of incidence will be equal to angle of emergence. That is angle i=angle eShe will ALSO observe that RATIO of sine of angle of incidence to sine of angle of refraction is a constant.That is sin i/sin r=constantShe will draw the conclusion that the INCIDENT RAY is parallel to the emergent ray
