Explanation:
Refractive index of Zircon and Quartz varies as below
Zircon:
Quartz:
For this problem the refractive indices of samples are assumed as lowest.
From Snell's law we know that when a beam passes from a medium
#n_1 sin theta_1 = n_2 sin theta_2#
Inserting given values we get
#1.81 sin 8^@= 1.544 sin theta_2#
#=> sin theta_2=(1.81 sin 8^@)/1.544#
#=> theta_2=sin^-1 ((1.81 sin 8^@)/1.544)#
#=9.4^@# , rounded to one decimal place.
