Question

a black spot on the surface of the glass sphere of refractive index musical to 3 by 2 is viewed from diametrically opposite position it appears to be at a distance of 10 cm from the spot diameter of the serous​

Answer 1

Answer:

Diameter of the sphere is 5 cm

Explanation:

As we know that the position of the image from the surface is given as

$d_i = 10 cm$

refractive index is given as

$\mu = \frac{3}{2}$

now from the formula

$\frac{\mu_2}{d_i} - \frac{\mu_1}{d_o} = \frac{\mu_2 - \mu_1}{R}$

now we know that

$\frac{1}{10} - \frac{1.5}{2R} = \frac{1 - 1.5}{R}$

$\frac{1}{10} = \frac{3}{4R} - \frac{1}{2R}$

$\frac{1}{10} = \frac{1}{4R}$

$R = 2.5 cm$

so diameter of the sphere is 5 cm
