How to draw the first and second principal planes for ball lens?
Sketch the locations of the second and first principal planes for the hemispherical lens when it is placed with its flat surface facing the light and spherical lens.
Determine the principal planes and the principal stresses for the state of plane stress resulting from the superposition of the two states of stress shown. Given: X=12 ksi. 14 ksi 12 ksi 45° + + X The orientation of the principal plane in the first quadrant is 176 The orientation of the principal plane in the second quadrant is The maximum principal stress is 35 ks, and the minimum principal stress is - ksi.
Optics question...there are principal points (P, P’), principal planes (H, H’), and vertex surfaces (A, A’) in a lens system. *Which one(s) of these have a numerical number, and why?* Also, my notes are a bit confusing, are these points only in the picture when LM=1, or LM can be anything? Thank you!
Two thin lenses with focal lengths of magnitude 18.0 cm, the first diverging and the second converging, are placed 11.00 cm apart. An object 3.70 mm tall is placed 4.75 cm to the left of the first (diverging) lens. (a) Where is the image formed by the first lens located? (b) How far from the object is the final image formed? (c) Is the final image real or virtual? (d) What is the height of the final image? (e) Draw...
For the following question, draw a ray diagram for each lens draw a careful and accurate ray diagram of this image (from lens 1) as an object (for lens 2) forming an image through the second lens. Finally, draw a careful and accurate ray diagram of the entire situation, including both lenses and all images. An object 5 cm high is located 75 cm from a converging lens (X1 = 75 cm) of focal length f1 = 50 cm. A...

7.57 Determine the principal planes and the principal stresses for the state of plane stress resulting from the superposition of the two states of stress shown. Fig. P7.57
Draw a ray diagram for the following situation (an object far from the lens) involving a diverging lens. The ray tracing needs to have the three principal rays. Also, draw the image on the ray diagram where the three principal rays converge. Refer to Section 26.4 of Serway & Jewett for further guidance on how to construct principal rays. Use a ruler to measure the object distances, image distances, and focal lengths for the ray diagram. Then, verify that your...
Two lenses are placed on an optical axis. The first lens is a has a focal length of fı = -9.0 cm and the second lens has a focal length of f2 = 16 cm. The two lenses are separated by 24 cm. A 4 cm tall object is placed 5 cm in front of the first lens. “In front of means it is not between the lenses. a) Draw a picture of the setup b) Find the image position...
