Your question is missing one part as "magnification"

i have completed the missing part below

Answer:

a. d_{i}=-0.0566cm

b. M=441.69

Explanation:

For this type of numerical we will use the following formulas

\frac{n1}{d_{o} }+\frac{n_{2} }{d_{i} }=\frac{n_{2}-n_{1}  }{R}......... Eq1

where,

n_{1}=refractive index of the medium surrounding refracting surface/object

i.e. n_{1}=n_{air}  

n_{2}= refractive index of the refracting surface/object

i.e. n_{2}=n_{glass}

d_{0}= distance of object from the vertex of the refracting surface

d_{i}=distance of image from the vertex of the refracting surface

R=radius of curvature of the refracting surface

M=\frac{d_{0} }{d_{i} } ........... Eq2

where,

M=magnification

Convention:

R>0\for\ the\ convex\ refractive\ surface\ of\ curvature\\\ R

Given:

n_{1}=n_{air}=1.0

n_{2}=n_{glass}=1.5

d_{0}=25cm

R=-11cm because refraction surface is concave

Required:

a. d_{i}=?

b. M=?

Solution:

a. putting values in eq1, we get

\frac{1.0}{25}+\frac{1.5}{d_{i} }=\frac{1.5-1.0}{-11}

\frac{1.5}{d_{i} }=-0.045-0.040

d_{i}=(-0.085)(\frac{1}{1.5} )

d_{i}=-0.0566cm

b. M=\frac{25}{-0.05665}

M=441.69
