Question

Question The prism of refracting angel 60 and meup =1.5 has angel of refraction 25 at first face. Angel of incidence at second face is​

Answer 1

Explanation:

The ray will not emerge out of his prism

We have, δ=(μ−1)A

=(1.5−1)×90

=0.5×90

=45

o

Now, δ=(i

=45−30+90

=105

o

Angle of emergence has inclination with second surface

=90−105

=−15

This shows that light ray will not emerge out of the prism.
