- Two thin lenses with focal lengths of magnitude 15.0 cm, the first diverging and the second converging, are placed 12.00 cm apart. An object 3.00 mm tall is placed 5.50 cm to the left of the first (diverging) lens. Where is the image formed by the first lens located? Please provide a detailed explanation of the process. How far from the object is the final image formed? Please describe the steps taken to reach to your conclusion.Question 2 A 0.800-cm-tall candle flame is 1.90 m from a wall. You happen to have a lens with a focal length of 22.0 cm, and notice while playing around with it that there are two locations you can place the lens and form a well-focused image of the candle flame on the wall. With the lens in the location furthest from the wall, what is the height of the image? (Input a positive height):Create a ray diagram for eyeglasses that contain a diverging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm. What type of vision are they used to correct? Give both names. How do they do this? Explain.
- How could you very quickly make an approximate measurement of the focal length of a converging lens? Could the same method be applied if you wished to use a diverging lens? Explain.4.To measure the focal length of a diverging lens, a converging lens is placed in contact with it as shown to the right. The sun's focused by this Image point made by first lens (object point for second lens) are rays combination at a point 28.5 cm behind Image made by second lens the lenses. If the converging lens has a focal length fc of 16 cm, what is the focal length of the diverging lens? (final image) fc -fr =28.5 cmAnne's retina is 1.8 cm from the lens. The nearest object she can see clearly without corrective lenses is 2.0 m away. 1. Sketch a ray diagram to show (qualitatively) what happens when she tries to look at something closer than 2.0 m without corrective lenses. 2. What should the focal length of her contact lenses be so that she can see clearly objects as close as 20.0 cm from her eye?
- A certain slide projector has a 118-mm-focal-length lens. Hints Follow the problem-solving strategy steps outlined in "Problem-Solving Strategy: Lenses" in Section 2.4 Thin Lenses. Two additional hints: (1) you are given the focal length and object distance-distance to slide-here; what equation relates these to the image distance? (2) Remember the linear magnification formula. a. To project the image of a slide onto a screen, does this lens need to form a real image or a virtual image? not enough information given virtual image real image b. If a slide is placed 123 mm from the lens, how far from the lens should the screen be placed for a sharp image? mm away from lens. c. If the size of the slide is 36.0 (width) by 24.0 (height) mm, what are the dimensions of the image? Width = mm; Height = mm The film should be positioned at the location of the image to record the image.Please don't provide handwritten solution.... A diverging lens with f = -37.5 cm is placed 15.0 cm behind a converging lens with f = 21.0 cm .Where will an object at infinity be focused? Determine the image distance from the second lens. Follow the sign conventions.
