Question

For the first two sets of data points only, use image and object distances to find the magnification at each position of the lens (magnification = M = -i/o). Then using your measurements of the image and objects sizes, find the magnification by the measured image and object sizes. (?M? = (image size)/(object size). Compare and comment on the four values of M. (10 points)

Answer 1

For the first two sets of data points only, use image and object distances to find the magnification at each position of the lens (magnification M-i/o). Then using your measurements of the image and objects sizes, find the magnification by the measured image and object sizes. (EM(image size)/(object size). Compare and comment on the four values of M. (10 points) magnification-- image diatnce/ object distance and magnification can only be calculated if object height and image height is given Object distance (cm) Image distance (cm) 1/do 1/di magnification- image height/object height 89.4 110 80.3 128.5 75.2 144 72.1 157.5 83 164 109.3 89.4 128.5 86.3 144 75 157 71.5 163.3 70.3 0.011 0.009 0.012 0.008 0.013 0.007 0.014 0.006 0.014 0.006 0.009 0.011 0.008 0.012 0.007 0.013 0.006 0.014 0.006 0.014 For first two data we will use magnification- - di/do 1-22. dli 27 Ч 2 ml is more than 1 so we get larger inage than object m2 is less than 1 so we get smaller image than object from both we get inverted image as we get negative sign with this
