Answer -
The incident, refracted,and emergent rays associated with a glass prism ABC are shown in the givenfigure.
Angle of prism, тИаA┬а= 60┬░
Refractive index of the prism,┬а┬╡┬а=1.524
┬а= Incident angle
┬а= Refracted angle
┬а= Angle of incidenceat the face AC
e┬а= Emergent angle = 90┬░
According to SnellтАЩs law,for face AC, we can have:
It is clear from the figure that angle
According to SnellтАЩs law,we have the relation:
Hence,the angle of incidence is 29.75┬░.
