A light ray - shown in the lower left part of the figure - approaches and then hits the boundary. Part of the ray reflects back to glass \( A \), part of the ray enters glass \( B \). The index of refraction of glass \( A \) is \( n_{A}=1.190 \). Determine the index of refraction of glass B. (Notice that the lines representing the light rays travel through grid intersection
