Q 15: A camera with a 7.0-cm focal length lens is used to photograph a person who is 2.0 m tall. The height of the image on the film must be no greater than 7.0 cm. Calculate the closest distance the person can stand to the lens. Q 19: A man who can produce sharp images on his retina only of objects that lie from 55 cm to 290 cm from his eyes needs bifocal lenses. Determine the desired focal...
You have a camera with a fixed lens-to-film distance = 6.0 cm. What focal length lens is needed to take a picture of an object located 4.0 m in front of the camera lens?
A 5 cm tall object stands in front of a converging lens with focal length f = 35 cm. The distance between the object and the lens is 10 cm. (a) Give the power of the lens. (b) Calculate the position and height of the image formed. Is the image real or virtual? (c) In the space below clearly produce the ray diagram (at least two of the three rays that form the image). A farsighted person uses spectacles formed...
- Consider a camera that uses a lens with a focal length of 35 mm. How far behind the lens must the film be in order to take a picture of a flower that is 75 cm in front of the lens? - A convex lens is used to make an image of a 10 cm tall arrow on a screen. The arrow sits 25 cm in front of the lens and the image that it creates is 20 mm...
An object 3.75 cm tall stands 20.0 cm in front of a diverging lens of focal length magnitude 15.0 cm. a) Find the image distance. b) Find the image height. c) Is the image real or virtual? Explain in detail. d) Is the image erect or inverted? Explain in detail.

3. A 4.0-cm candle is placed 30 cm in front of a camera lens of focal length of 25 cm. (a) Determine the position where its image formed. (b) Determine the size of its image. (c) Draw a ray diagram - Indicate all the rays clearly. Label object distance, image distance, focal length. (d) Describe the type of image formed.
A 4.0 cm tall object is 5.0 cm in front of a diverging lens with a focal length of -6.0 cm. A converging lens with a focal length of 6.0 cm is located 8.0 cm behind the diverging lens. (As viewed from the side, from left to right, the sequence is object - diverging lens - converging lens - observer. Rays then travel from left to right through the system.) (a) Use ray tracing to draw image 1 and image...
An object is placed 6.0 cm in front of a lens of focal length 5.0 cm. Another lens of focal length 4.0 cm is placed 2.4 cm behind the first lens. (a) Where is the final image? distance cm location ---Select--- behind the second lens in front of the second lens, but between lenses in front of the first lens Is the image real or virtual? virtualreal (b) What is the overall magnification?
