⭐Find-⭐

• Height through which image of stamp is raised??

⭐Given-⭐

• Refractive index of glass = 1.54

• Real depth= 3 cm

⭐formula-⭐

• $\boxed{refractive\ index= \dfrac{real\ depth}{apparent\ depth}}$---(1)

• $\boxed{Height=real - apparent \ depth}$----(2)

⭐Solution-⭐

• Putting values in formula (1) we get

$1.54= \dfrac{3}{ apparent\ depth}$

$apparent\ depth = 1.94cm$

• Using (2) formula,we get the height

that is

$h= 3-1.94= 1.06cm$

Hence, answer will be 1.06cm
