Consider a configuration of a identical units, each consisting of three layers. The first layer is a column of height h=1/3 cm, and the second and third layer are equal thickness d=[SQRT(3)-1]/2 cm, and refractive indices n1=SQRT(3/2) and n2=SQRT(3) respectively. A light source O is placed on top of the first unit. A ray of light from O is incident on the second layer of the first unit at the angle of theta=60 degree to the normal. For a specific value of n, the ray of light emerges from the bottom of the configuration at distance l=8/SQRT(3) cm. The value of n=?
