Question

glass block 3 cm is placed over a stamp calculate the height through which image of the stamp is raised Refractive Index of a glass is 1.54​

Answer 1

Given that,

Refractive index of glass = 1.54

Real depth= 3 cm

We need to calculate the apparent depth

Using formula of height

$\mu=\dfrac{real\ depth}{apparent\ depth}$

Put the value into the formula

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

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

$apparent\ depth=1.94\ cm$

We need to calculate the height through which image of the stamp raised

Using formula of height

h = real depth - apparent depth

Put the value into the formula

$h =3 -1.94$

$h =1.06\ cm$

Hence,  The height through which image of the stamp raised is 1.06 cm.
