The size of the image is 0.556 cm.
Explanation:
Given that,
Height of the object, h = 5 cm
Radius of curvature of the concave mirror, R = 40 cm
Focal length, f = -20 cm
Let the object is placed at a distance of 200 cm, u = -200 cm
To find,
Size of the image
Solution,
Let v is the distance of image from the mirror. Using mirror's formula to find it as :
v = -22.23 cm
The image is located at a distance of 22.23 cm.
Let h' is the size of image. It can be calculated using formula of magnification as :
h' = -0.556 cm
So, the size of the image is 0.556 cm.
