Explanation of Solution
Write the expression for the refraction at a spherical surface.
Here,
Rearrange the equation (I) for
Write the expression for the magnification for a refractive surface.
Here,
Write the expression for the total magnification for a thick lens.
Here,
Conclusion:
Substitute
The positive sign indicates that the image is formed on the right side of surface 1.
Substitute
The image formed by surface 1 acts as the object for the surface 2. Thus, the object distance for surface 2 is,
Substitute
The positive sign indicates that the image is formed behind the surface 2.
Substitute
Substitute
Therefore, the distance of the screen from the surface 2 is

- People who do very detailed work close up, such as jewelers, often can see objects clearly at much closer distance than the normal 25 cm. (a) What is the power of the eyes of a woman who can see an object clearly at a distance of only 8.00 cm? (b) What is the image size of a 1.00-mm object, such as lettering inside a ring, held at this distance? (c) What would the size of the image be if the object were held at the normal 25.0 cm distance?arrow_forwardIn Figure P35.30, a thin converging lens of focal length 14.0 cm forms an image of the square abed, which is he = hb = 10.0 cm high and lies between distances of pd = 20.0 cm and pa = 30.0 cm from the lens. Let a, b, c. and d represent the respective corners of the image. Let qa represent the image distance for points a and b, qd represent the image distance for points c and d, hb, represent the distance from point b to the axis, and hc represent the height of c. (a) Find qa, qd, hb, and hc. (b) Make a sketch of the image. (c) The area of the object is 100 cm2. By carrying out the following steps, you will evaluate the area of the image. Let q represent the image distance of any point between a and d, for which the object distance is p. Let h represent the distance from the axis to the point at the edge of the image between b and c at image distance q. Demonstrate that h=10.0q(114.01q) where h and q are in centimeters.
