Q1:An object whose height is 3.7 cm is at a distance of 9.5 cm from a spherical concave mirror. Its image is real and has a height of 10.7 cm. Calculate the radius of curvature of the mirror. A:1.41?101 cm Q2:How far from the mirror is it necessary to place the above object in order to have a virtual image with a height of 10.7 cm? A:? Please answer question 2 and show all work.Explanation / Answer
Here ,
radius of curvature = 14.1 cm
focal length , f = r/2
f = 14.1/2
f = 7.05 cm
Now, for hi = 10.7 cm
hi/ho = -di/do
10.7/3.7 = -di/do
di = -2.89do
Using mirror formula
1/f = 1/di + 1/do
1/7.05 = -1/2.89do + 1/do
do = 4.61 cm
the object should be placed at 4.61 cm away
