How can an out-of-focus image refected in the camera obscura be brought into focus
Step by step
Solved in 2 steps
- A pebble 1 cm tall is placed 40 cm to the left of a +5-diopter lens. A -5-diopter lens is placed 30 cm to the right of the first lens. Where will the final image be located, and will it be real or virtual? What will be the size of the final image, and will it be erect or inverted?A typical 20-year-old student has a far point of infinity and a near point of about 10 cm. (Try it and see. Pick one eye, and see how close to your eye you can hold this book while keeping it in sharp focus.) What change in power is needed to focus at the 10 cm near point?calculate final image location w/ respect to second lens and calculate magnification factor using double lens system
- A 10-cm-tall object is located in front of a diverging lens with a power of -5 diopters. 1) Calculate the image height hI if the object is located 42 cm from the lens. Follow the sign convention. (Express your answer to two significant figures.) 2) Is the image upright or virtual?You use your 8× binoculars to focus on a yellow-rumped warbler (length 14 cm) in a tree 18 m away from you. What angle (in degrees) does the image of the warbler subtend on your retina?How do you focus an image that has been distorted by the camera obscura?
- Where is the near point of an eye for which a contact lens with a power of 2.60 diopters is prescribed? (Assume that near point for an average viewer is 25 cm .) Where is the far point of an eye for which a contact lens with a power of -1.20 diopters is prescribed for distant vision?An object 2cm high is placed 6cm away from a converging lens of focal point 10 cm. By means of a carefully drawn scale diagram, find the nature, position, and size of the image'.Discuss the concept of chromatic aberration in lenses. How can it be minimized or corrected in optical systems?
