- Consider an underwater spherical air bubble (you can assume the index of refraction of air is 1 and water is 1.33) with radius R. This bubble can act as a lens. Is it a converging or diverging lens and why? What is the focal length?A camera lens usually consists of a combination of two or more lenses to produce a good-quality image. Suppose a camera lens has two lenses - a diverging lens of focal length 10.7 cm and a converging lens of focal length 5.35 cm. The two lenses are held 6.79 cm apart. A flower of length 10.7 cm, to be pictured, is held upright at a distance 54.3 cm in front of the diverging lens; the converging lens is placed behind the diverging lens. a) How far to the right of the convex lens is the final image? Submit Answer Tries 0/100 b) What is the magnification of the final image? Submit Answer Tries 0/100 c) And what is the height of the final image? Submit Answer Tries 0/100An object is placed 20 cm to the left of a converging lens of focal length 30 cm. A diverging lens of focal length 15 cm is 25 cm to the right of the converging lens. Find the position and magnification of the final image. Object f₁ 42
- A 2.0-cm-tall object is 23 cm in front of a converging lens that has a 40 cm focal length. Calculate the image position. Calculate the image height. Type a positive value if the image is upright and a negative value if it is inverted.An object is placed 40 cm in front of a converging lens that has a 60-cm focal length. Where will the image be formed? Select answer from the options below 24 cm in front of the lens 120 cm in front of the lens None of the choices are correct. 120 cm behind the lens 24 cm behind the lensA 3.0-cm-tall object is 13.5 cm in front of a diverging lens that has a -25 cm focal length. Calculate the image height. Type a positive value if the image is upright and a negative value if it is inverted.
- A candle is placed at a fixed distance D from a screen. A converging lens can be put between the screen and the candle, at a variable distance x from the candle. Assume a sharp image occurs on the screen. (A) If the magnification is 2, what is x? (B) If the magnification is 1/2, what is x? (C) What is the focal length of the lens? HINT: Draw ray diagrams. D = 87 cm. Clarification: the absolute value of the magnification is either 2 or 1/2.]A thin lens has two focal points, one on either side, at equal distances from its center, and should behave the same for light entering from either side. Look through your eyeglasses (or those of a friend) backward and forward and comment on whether they are thin lenses.One method of measuring the focal length of a lens is to form an image of an object that is many focal lengths away from the lens. Show from equation (1/f=1/o+1/i) that the image distance is approximately equal to the focal length when the object distance is very large (say, o=100f). What happens when the object distance become infinitely far away?
- A convex lens has a focal length of 8 cm. An object that is 4 cm tall is placed at unknown distance from the lens and produces a virtual image that is 6 cm away from the lens. What is the distance of the object from the lens? What is the magnification? Is the image upright or inverted?A diverging lens is located 14 cm to the left of a converging lens. A 3.44-cm-tall object stands to the left of the diverging lens, exactly at its focal point. Determine the distance of the final image relative to the converging lens, in cm. Diverging lens 1 focal length = -7 cm Converging lens 2 focal length = 32 cm Object F1 Lens 1 Round to nearest whole number Lens 2 Eye AA 1 [cm] tall object is 50 [cm] away from a converging lens of focal length f = 30 [cm]. A second converging lens of focal length f = 80 [cm] is placed 2 [m] behind the first lens. a) Where is the image formed by the first lens (ignoring the second lens)? How big is it? b) Now, this image is the object for the second lens. Where is the second (final) image formed by the second lens? How big is it?
