Explanation:
Given that,
Height of object = 4.0 cm
Distance of the object u= -30.0 cm
Focal length = 23 cm
We need to calculate the image distance
Using lens's formula
Where, u = object distance
v = image distance
f = focal length
Put the value into the formula
We need to calculate the height of the image
Using formula of height
Where, h' = height of image
h = height of object
The image is real and inverted.
(b). Now, object distance u = 13.0 cm
We need to calculate the image distance
Using lens's formula
Put the value into the formula
We need to calculate the height of the image
The image is virtual and erect.
Hence, This is required solution.
