A 4.0 cm tall object is placed 12.0 cm in front of a diverging lens. When the image of the object is measured it is found to measure 1.3 cm in height. What is the focal length of the lens? Draw a ray diagram with the object, image and focal points labeled.
An object is placed 100 cm in front of a lens of focal length 20 cm. A second lens is placed 35 cm beyond the first, this second lens having a focal length of 8.0 cm. If the size of the object is 6.0 cm, what is the size of the final image? Draw ray diagram and apply thin lens formula
A 5 cm tall object stands in front of a converging lens with focal length f = 35 cm. The distance between the object and the lens is 10 cm. (a) Give the power of the lens. (b) Calculate the position and height of the image formed. Is the image real or virtual? (c) In the space below clearly produce the ray diagram (at least two of the three rays that form the image). A farsighted person uses spectacles formed...
A 4.0-cm tall object is placed 50.0 cm from a diverging lens having a focal length of magnitude 25.0 cm. Draw the ray diagram for this situation. What is the location and height of the image? Is the image real or virtual? • Draw an optical axis with the lens centered on the axis. Represent the object at the correct distance from the lens • Draw the three "special rays" from the top of the object • Extend the rays...
CHAPTER 33 Problem 33.1 A lighted candle is placed 36 cm in front of a converging lens of focal length fi 13 cm, which in turn is 56 cm in front of another converging lens of focal length f2 16 cm. (a) Calculate the position of the final image. (b) Calculate the relative size of the final image Express your answer to two significant figures and include the appropriate units. Lens 1 Lens 2 O Ft CHAPTER 33 Problem 33.1...
2. A thin converging lens has a focal length of 10.0 cm. An object is placed 30.0 cm from this lens. Use a sheet of the graph paper provided at the back of this manual to draw a ray diagram that shows the image formed by this lens. Use any two of the three principal (or special) rays and an appropriate scale. Hint: you could let 1 cm on your ray diagram represent 5 cm of the actual measurements:this scale...
An object is placed in front of a diverging lens with focal length of −70 cm. Find the location of the image and the characteristics of the image (real or virtual, enlarged or reduced, and upright or inverted) for each object distance. Also draw the ray diagram for each object distance. a) 100 cm b) 40 cm
An object is located 40.0 cm from the front side of a divergent lens. A focal point of the lens is located at 20.0 cm from the front side of the lens. (a) Determine the location of the image formed. (b) Determine the size of the image if the object is 12.0 cm tall. (c) Draw a ray tracing diagram showing the location of the object, image and lens. An object is located 40.0 cm from the front side of...
A 4.0 cm tall object is 5.0 cm in front of a diverging lens with a focal length of -6.0 cm. A converging lens with a focal length of 6.0 cm is located 8.0 cm behind the diverging lens. (As viewed from the side, from left to right, the sequence is object - diverging lens - converging lens - observer. Rays then travel from left to right through the system.) (a) Use ray tracing to draw image 1 and image...
Problem 8. An object is placed 10 cm in front of a diverging lens of focal length -5 cm. A) Find the position and magnication of the image using the thin lens equations. B) Verify your answer to part A) with a ray trace. Use three rays.
