(a) An object that is 2.73 cm high is placed 25.3 cm in front of a...
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
3. An object 3cm high is placed 40cm in front of a thin +10.00D lens. Find the [30] position and size of the image. (Note: a diagram is needed for this question.) 4. The object in Q3 is moved so that it lies 20cm in front of the lens. Find the new position and size of the image [30] (Note: a diagram is needed for this question.) 5. The object in Q3 is now moved so that it lies 8cm...
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.
An object 1.50 cm high is placed a distance of 31.2 cm in front of a converging MIRROR having focal length 13.5 cm. a) Determine the image distance. b) Determine the magnification of the mirror b) Determine the image characteristics (real/virtual, upright/inverted, size). c) Draw an accurate ray diagram of this situation. d) If the object is moved to a distance of 15.8 cm from the mirror, determine the location of the image. e) At what distance from the mirror...
3. A 4.0-cm candle is placed 30 cm in front of a camera lens of focal length of 25 cm. (a) Determine the position where its image formed. (b) Determine the size of its image. (c) Draw a ray diagram - Indicate all the rays clearly. Label object distance, image distance, focal length. (d) Describe the type of image formed.
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.
What is the position of the image of a 5-cm-high object placed 25 cm from a +5.0-cm-focal-length converging lens? Draw a ray diagram. 9.
An object is 4 cm high and is located 17 cm in front of a thin
converging lens with a focal length of 12 cm.
a. Calculate the position (distance from the center of the lens)
of the image.
b. Calculate the image height (including sign).
Suppose a 1.5 cm tall object is placed 3.50 cm in front of a diverging lens with focal length -2.00 cm. Draw a ray diagram that accurately shows the image. The image is {a. upright b. inverted}. The image is {a. real b. virtual}.
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
