Explanation of Solution
Given:
An object is placed before a thin lens as follows :
Formula used :
In similar triangles ABC and DEF , corresponding sides are in equal proportions or,

- Thank you so much in advance. The diagram shows a lens with a positive focal length 11 cm. (a) If we place an object at a distance of 25 cm from the lens, where will the resulting image position on the other side of the lens be found? Include units in answer, (b) With the object at 25 cm from the lens, what will the magnification be for the image at this position? (c) If we place an object at a distance of 4 cm from the lens, where will the resulting image position be found? (d) With the object at 4 cm from the lens, what will the magnification be for the image at this position?arrow_forwardA 1.5 cmcm high object is located 30 cmcm from a diverging lens, whose focal length is 11 cmcm . What is the height of the image produced by the lens? You have determined the height of the image using numerical methods and, in so doing, have also determined its position, s′s′s'. Now, use graphical methods to evaluate your results.The diagram below shows the object, a ray (ray 1) parallel to the optic axis of the lens, and a ray (ray 2) proceeding toward the first focal point of the lens. Draw the refracted rays and the image produced by the lens. Make sure you extend the refracted rays sufficiently backward in order to find the image. Keep in mind that principal-ray diagrams must be drawn accurately to give good results!arrow_forwardIn this example, we will find the position and magnification of an image formed by a spherical mirror. A lamp is placed 10 cmcm in front of a concave spherical mirror that forms an image of the filament on a screen placed 3.0 mm from the mirror. What is the radius of curvature of the mirror? What is the lateral magnification? If the lamp filament is 5.0 mmmm high, how tall is its image? SOLUTION SET UP (Figure 1) shows our diagram. SOLVE Both object distance and image distance are positive; we have ss = 10 cmcm and s's′ = 300 cmcm. To find the radius of curvature, we use the following: 1s+1s′110cm+1300cm==2R, and RR = 19.4 cmcm. The lateral magnification mm is obtained from m=y′/y=−s′/s m=y′y=−150mm5mm=−30. To find the height of the image, we simply multiply the height of the object by the magnification: y′=−30×5.0 m=150m REFLECT The image is inverted (as we know because m = -30 is negative) and is 30 times taller than the object. Notice that the filament is not located at the…arrow_forward
- The provided image shows the steps to find the ray transfer matrix for a thick biconvex lens (n=1.5) with a radius of curvature for the front and back face of 10cm. If this was a thin lens, then element C of the ABCD matrix would equal -1/f. What thickness t gives you a 10% change in this C value?

Draw the following rays in the figure: ray parallel to the optical axis, focal ray, central ray, draw the image of the arrow, indicate in the same figure from where to where di is (image-lens distance). Don't forget to put the direction on each ray, both the incident rays and the transmitted rays. Image characteristics for case 7: object located at d0 > 2F'.

Part (a) An object is placed a distance do,1=22 cm to the left of lens 1 which has focal length F1=4.2 cm. Ignore the existence of lens 2 for the moment.
