Question

A plane glass mirror of thickness $$3$$ cm of material of μ$$=$$ $$3/2$$ is silvered on the back surface. When a point object is placed $$9$$ cm from the front surface of the mirror, thenthe position of the brightest image from the front surface is

Infinity Learn · Accepted Answer

A thick glass mirror produces a number of images.There is an apparent shift of actual silvered surface toward the unsilvered face.Effective distance of the reflecting surface from unsilvered face $$=d$$μ$$=33/2cm=2cmDistance$$ of the point object from effective reflecting surface $$=$$ $$9$$ cm $$+$$ $$2$$ cm $$=$$ $$11$$ cm.Distance of image from the point object $$=$$ $$11$$ cm $$+$$ $$11$$ cm $$=$$ $$22$$ cmDistance of image from unsilvered face $$=$$ (22-$$ $$9) cm $$=$$ $$13$$ cm

A plane glass mirror of thickness 3 cm of material of $μ$ = 3/2 is silvered on the back surface. When a point object is placed 9 cm from the front surface of the mirror, then
the position of the brightest image from the front surface is
