A converging beam is incident on a system of two glass slabs with refractive indices \( \mu_{1}=(3 / 2), \mu_{2}=(5 / 4) \) and a concave mirror placed at a distance \( l \) from the closest face of the slab 2. The observer \( O \) receives the reflected rays from the system and perceives that the image is formed at \( P \) itself (see figure) which is also the point of convergence of the incident beam (extrapolated). If the concave mirrors focal length is \( 20 \mathrm{~cm} \). Find the value of \( l \) in \( \mathrm{cm} \).
