Pls. hep me answer these questions and show solution Thanks
1.You have a converging (convex) lens and a diverging (concave) lens and the magnitude of the focal length of each lens is 44.4 cm.Determine how far from the lens you should locate the screen in order to produce an image of the light bulb that is magnified by a factor of 1.55. (Answer in m)
2.A lens is needed to provide an image with a height of −6.80 cm. The object is a person who is 1.60 m tall standing 7.1 m away from the lens. What is the focal length of the lens in cm?

The lens shown above is a O bi-convex diverging lens. bi-convex converging lens. bi-concave diverging lens. Obi-concave converging lens. Under the sign convention rules for lenses, a negative focal length means that the lens is planar. converging. bifocal. diverging. An object is placed 30 cm from a converging lens with a focal length of 20 cm. The image will appear right side up 12 cm from the lens on the same side of the lens. right side up 60 cm...
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?
1. A 1.0-cm-tall object is 85cm in front of a converging lens that has a 35cm focal length. Calculate the image position and image height. 2. A 4.0-cm-tall object is 16cm in front of a diverging lens that has a -20cm focal length. Calculate the image position and image height. 3. A 4.0-cm-tall object is 14cm in front of a concave mirror that has a 25 cm focal length. Calculate the image position and image height.
1. You are standing 3.0 m from a convex (diverging) security mirror in a store. You estimate the height of your image to be one-quarter (0.25) of your height. How far from the mirror is your image located include direction)2 A) 0.75 m B) 1.3 m C) 3.0 m D)-3.0 m E)-1.3 m F)-0.75 m 2. In problem 1, the focal length of the mirror is: A) 12 m B)-12 m C) 0.083 m D) -0.083 m E)-1.0 m F)...
2. Two thin lenses, one a converging lens and the other a diverging lens, are arated by 1.00 m along the same principal axis, as shown in the figure. The magnitude of the focal length of the converging lens is 25 cm, while the magnitude of the focal length of the diverging lens is 40 em. An object 8,25 cm tall is placed 35 cm to the left of the converging lens. (a) Where is the final image produced by...
1.A convex (converging) lens produces a real, inverted image of an object that is magnified 2.80 times when the object is 43.0 cm from the lens. What is the focal length of the lens? 2. The closest distance a book can be read from a pair of reading eyeglasses (Power = 1.63 dp) is 29.0 cm. What is the near distance?(Assume a distance between the eyeglasses and the eyes to be 2.50 cm)
2) A diverging lens is placed 20. cm away from an object, 80. cm from the diverging lens is a converging lens whose focal length is 25 cm. 35. cm from the converging lens is a screen showing an image of the object. a) What is the focal length of the diverging lens? f = 25. cm o *20. cm → 80. cm + 35 cm → b) What type of image is it? Circle one Real or Virtual c)...
An item is 20 em from a lens with a focal length of +12 em (convex lens). How far away must the screen be to produce a focused image, and what is the magnification of the image? Draw a rough picture of where the image is in relation to the object and the lens. 1. An item is 8 cm from a lens with a focal length of +12 cm (convex lens). Where does a focused image form? Can it...
a convex (converging) lens of focal length 6 centimeters as shown in the picture: 6 cm to locate the Image. Draw an arrow that represents the image. )(or redraw to the exact scale here) b. Is the Image real or virtual? Explain your choice. (2) c. Using the lens equation, compute the distance of the image from the lens. (2)
