Homework Statement
An object is placed 21 cm in front of a concave mirror of radius of curvature of 10 cm. A glass slab of thickness 3 cm and RI =1.5; is then placed close to the mirror. Find the position of the final image.
Take distance of closer side of block as 1 cm from the mirror.
Homework Equations
##\frac{1}{f}= \frac{1}{u} + \frac{1}{v}##
u is the object dist. and v is the image dist.
##lateral~ shift~=~t\frac{\sin(i-r)}{\cos(r)}##
The Attempt at a Solution
Ignoring the block i get ##v = -6.56 cm##
I don't know how to consider the block... i tried this..
i need the length of B'B'₂
I have the measure of a perpendicular drawn from A' to the line through A'₂ which was suppose to go through the focus..
