Physics - Geometrical Optics Question with Solution | TestHub

Three right angled prisms of refractive indices ${\mathrm{n}}_1,{\mathrm{n}}_2$ and ${\mathrm{n}}_3$ are fixed together using an optical glue as shown in figure. If a ray passes through the prisms without suffering any net deviation, then-\\

${\mathrm{n}}_1={\mathrm{n}}_2={\mathrm{n}}_3$${\mathrm{n}}_1={\mathrm{n}}_2\ne {\mathrm{n}}_3$$1+{\mathrm{n}}_1={\mathrm{n}}_2+{\mathrm{n}}_3$$1+{\mathrm{n}}_2^2={\mathrm{n}}_1^2+{\mathrm{n}}_3^2$
