A convex refracting surface f radius of curvature 20 cm separates two media of refractive indices 4/3 and 1.60. An object is placed in the first medium (n = 4/3) at a distance of 200 cm from the refracting surface. Calculate the position of the image formed.

Expert Answer:

R = 20 cm

n1 = 4/3 

n2 = 1.60 

u = -200 cm

Now, using the formula,

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

Hence, the image will be formed at 240 cm in denser medium.
