Question #ea4f0
1 Answer
We know the following relation of refractive index (
#mu=sin((del_m+A)/2)/sin(A/2)#
As per given condition we have
So we have
#mu=sin((A+A)/2)/sin(A/2)#
#=>mu=sinA/sin(A/2)#
#=>mu=(2sin(A/2)cos(A/2))/sin(A/2)#
#=>cos(A/2)=mu/2#
#=>A=2cos^-1(mu/2)#
If we take for glass
Then
If we think otherwise
This relation reveals that the value of
Imposing this condition we can have the maximum value of
Hence
