7. A lens of focal length 10cm is used to produce an image with magnification +3. What must the object distance be?
A lens of focal length 10cm is used to produce an image with magnification +3. What must the object distance be?
A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...
distance of image= 10cm Use the thin lens equation to determine the focal length. Assume that the object is infinitely far away.
A spherical lens has a magnification is +3.0. (a) Determine the focal length in terms of the object distance. (b) Suppose the object is located 6.0 cm to the left of the mirror. What are the focal length and image distance? (c) Is the lens concave or convex? (d) Using a ray diagram, confirm the locations of the image and focal point.
In the geometrical optics experiment, a student used a convex lens with 6 cm focal length to produce a large image of an object. The object was placed at a distance of 14 cm from the lens. What is the magnification of the image? include the sign.
A converging lens with a focal length of 40 cm is used to form an image on a screen that is 2.8 m behind the lens. At what distance in front of the lens must the object be placed?
The focal length of a convex lens is given to be 17 cm. It's magnification is -2.5. (a) What is the distance of the object and image from the lens? (b) What is the image height if the object is 15 cm? (c) Draw a ray diagram for this situation, label completely.
A concave lens has a focal length of -31 cm . Find the image distance and magnification that results when an object is placed 24 cm in front of the lens. A. What is the image distance? B? What is the magnification?
Problem 3 A lens with a focal length of 5 meters is used to look at an object that is x meters away, find the image distance, magnification, and whether the image is inverted or upright for the following values of x: a) x = 15 meters b) x = 2 meters c) If the object is placed at 5 meters away, find the image distance only. d) If the image distance is 5 meters away, find the object distance...
