Salt water Air RM R Lens S Screen Glass D K- Mirror K VHere is the translation without the initial numbering and point value: An industrial-grade flashlight is to be manufactured for use in the salty water of the Dead Sea, which has a refractive index . 1.375. This flashlight is to be designed with a plano-convex lens made of glass with a refractive index nn, 1.5. The thickness and the radius of curvature are the same value | | = 3cm. Alight bulb S (real object) will be fixed to a small non-reflecting screen and placed in front of a spherical mirror with a radius of curvature | ,,,| = 5cm. The distance between the edge of the lens and the mirroris L. = 8cm. At what distance ) from the edge of the lens should the light bulb be placed so that the rays reflected by the mirror exit the salty water parallel to the optical axis? Note: By virtue of the principle of reversibility, you can approach the problem by considering the saltwater as the source S or conversely, considering the source S as the saltwater, but be sure to clearly indicate each step of your calculation
