A 1.0-cm-tall candle flame is 2.0 m from a wall. You happen to have a lens with a focal length of 32 cm . How many places can you put the lens to form a well-focused image of the candle flame on the wall? What are the distance between the candle and the lens for each location? For each location, what is the height of the image?
A 1.5 cm tall candle flame is 1.7 m from a wall. You happen to have a lens with a focal length of 36 cm . 1- How many places can you put the lens to form a well-focused image of the candle flame on the wall? = 2 2- For each location, what is the height of the image and orientation of the image? = ?
You have a simple thin convex lens with at 15 cm focal length. To create a real inverted image of a candle with magnification of 2, how far should you place the candle from the lens? To create an upright virtual image with a magnification of 2, how far should you place the candle from the lens? Explain
You place a 22-cm focal length convex lens at a distance of 50 cm in front of a concave lens with a focal length of -42 cm. Then you place a small lightbulb (2 cm tall) 27 cm in front of the convex lens. Determine the distance from the second lens to the final image.
How far should an object be from a converging lens of focal length 35.0 cm to form a real image 1/4 its size?
You place a 22-cm focal length convex lens at a distance of 50 cm in front of a concave lens with a focal length of -40 cm. Then you place a small lightbulb (2 cm tall) 27 cm in front of the convex lens. Determine the distance from the second lens to the final image Express your answer with the appropriate units s'= it is NOT 20.44 or -20.44 cm
Two thin lenses with a focal length of magnitude 21.0 cm, the first diverging and the second converging, are located 15.8 cm apart. An object 3.50 mm tall is placed 35.0 cm to the left of the first (diverging) lens. 1)How far from this first lens is the final image formed? Express your answer in centimeters. 2)Is the final image real or virtual? 3)What is the height of the final image? Express your answer in millimeters. 4)Is it upright or...
You need to make a plano-concave lens with a focal length of +15 cm out of glass with an index of 1.60. Plano-concave means that one side is flat. You then form an image with the lens of an object that is 1 cm tall and that is 25 cm from the lens. (a) Find the radius of curvature of the curved side of the lens. (b) How far is the image formed from the lens? (e) How big is...
Asap Question 24 of 31 > You have a lens whose focal length is -5.87 cm. You place an object on the axis of the lens at a distance of 12.3 cm from it. How far is the object's image from the lens? Enter the answer as a positive quantity image distance: cm If it can be determined, is the image real or virtual? Oreal cannot be determined < Question 22 of 31 What is the focal length of 2.4...
Suppose you have a double convex lens with a focal length of 15 cm and want to use it to form an image of an object 30 cm from the lens. How far behind the lens will the image form when it is "in focus", as sharply defined as possible? Give your answer in cm.15
