An object is placed 15.0 cm to the left of a convex (converging) lens of focal length 20.0 cm. The image of this object is located (Figure out if the image is real or virtual, it will help to locate the image] O 60.0 cm to the left of the lens. O 60.0 cm to the right of the lens. O 8.57 cm to the right of the lens. O 8.57 cm to the left of the lens. Question 8...
Question 2 50 pts An object is placed at a distance f from a convex lens, wheref is the focal point. The size of the image is... Highly enlarged O Enlarged There is no image O Same size O Diminished
a) Using a ruler, draw an object placed between the focal point and the convex lens, and using principal rays, determine where the image is formed. b) Is the image larger or smaller than the object? c) Is the image upright or inverted? d) Is the image real or virtual? Explain. e) What could be a practical application of this? Question 2: Now examine the case of an object placed between the focal point and the lens:
A small object is placed 25.0 cm from a converging lens of focal length 40.0 cm. The object is to the left of the lens. Where is the image? A- 17cm to the right of the lens B- 25cm to the left of the lens C- 17 cm to the left of the lens D-25 cm to the right of the lens E-67cm to the right of the lens F-67 cm to the left of the lens A small object...
1.) An object is placed in front of a diverging lens with a focal length of 17.7 cm. For each object distance, find the image distance and the magnification. Describe each image. (a) 35.4 cm location _____cm magnification _____ nature real virtual upright inverted (b) 17.7 cm location _____ cm magnification _____ nature real virtual upright inverted (c) 8.85 cm location _____ cm magnification _____ nature real virtual upright inverted 2.) An object is placed in front of a converging lens...
An object is placed 12cm away from a convex lens that has a focal length of 5cm. a. Sketch a ray diagram for the situation. b. Is the image real or virtual, magnified or reduced, and upright or inverted? c. Determine where you should put a screen in order to project the image clearly. Is your answer consistent with the ray diagram? How do you know?
2. EAT 12B: A 2.50cm tall object is placed 15.0cm from a convex lens 1 point with a focal length of 12.6cm. Find the height of the image. Use the usual sign convention to indicate real/virtual and upright/inverted images. A. +1.4cm OB. -1.4cm C. +2.5cm OD. -2.5cm E. +13.1cm OF.-13.1cm
a small object is placed 25.0 cm from a converging lens of focal length 40.0cm.the object is to the left of the lens where is the image? same as the previous question. which statement is true about the image? It is real, upright and larger than the object It is virtual, upright and larger than the object. It is virtual, inverted and larger than the object. It is virtual, inverted and smaller than the object. It is real, inverted and...
A small object is placed to the left of a convex lens and on its optical axis. The object is 35 cm from the lens, which has a focal length of 15 cm. Determine the location of the image formed by the lens. (Enter your answer in cm from the lens.) Describe the image. (Select all that apply.) real virtual upright inverted enlarged reduced on the left side of the lens on the right side of the lens
1. The distance from the center of a lens to the location where parallel rays converge or appear to converge is called the length. convergence O meeting O focal O None of the above 2. When incoming rays are the focal point and the image point are the same. O parallel O from a nearby object O passing through the near side focal point O None of the above 3. A(n) image will not appear on a screen placed at...
