A convex lens produces a magnification of -2. This means the image is: A) Twice the...
In a converging (convex) lens, positive magnification m means the image is virtual, erect and lies in the same side of the object. positive magnification m means the image is real, inverted, and on the same side of the object. negative magnification m means the image is virtual, erect, and on the opposite side of the object.
A lens produces a real image of a real object. a) Is the image inverted or upright? b) Is the lens diverging or converging? c) Is the image enlarged or reduced in size? d) If two convex lenses identical in size and shape aremanufactured from glass with two different indices of refraction,would the focal length of the lens with the greater index ofrefraction (lens 1) be larger or smaller than that of the otherlens (lens 2)?
A positive magnification for a mirror means that the image is inverted, and the mirror is convex. the image is inverted, and the mirror could be either concave or convex. the image is upright, and the mirror is convex. the image is upright, and the mirror could be either concave or convex. the image is inverted, and the mirror is concave.
Based on the image, is the image real/virtual, inverted/upright, and what is the magnification? Object F F Plane mirror Convex lens
Problem 1. A concave-convex lens with index of refraction n = 3/2, radii of curvature R1 = ?3cm and R2 = 1cm is 4cm to the left of a diverging lens having focal length ?2cm. An object is placed to the left of both lenses at a distance 7 cm from the concave-convex lens. (a) Where is the final image formed by this combination of lenses? (b) Is the final image upright or inverted? (c) Is the final image real...
For a converging lens with focal length of 15 cm, an object at twice the focal length. Calculate the magnification of the image (Note: Negative means the image is inverted.) A. + 1 B. -1 C. +2 D. -2
A convex (converging) lens produces a real, inverted image of an object that is magnified 2.30 times when the object is 25.0 cm from the lens. What is the focal length of the lens?
A convex (converging) lens produces a real, inverted image of an object that is magnified 2.20 times when the object is 23.0 cm from the lens. What is the focal length of the lens?
Dealing with a lens and a real object, a positive magnification factor of the lens means that O O O O O the image will be taller than the object. that lens must be of the converging type. the object is farther from the lens than the image. the object distance will turn out to be positive. the image formed by the lens will be upright.
8. An object is placed 1 m in front of a convex lens with an 80 cm focal length. A convex mirror is then placed 1 m behind the lens. The radius of curvature of the mirror is 50 cm. 1. Where is the final image of the object (the image formed by light that has passed through the lens twice), with respect to the lens? 2. What is the total magnification of the final image? 3. Is the image...
