The magnification of an image formed by a convex lens is given by the formula:
m = -v/u
where m is the magnification, v is the image distance, and u is the object distance.
In this case, the object distance is given as 16 cm, so u = 16 cm.
Let's assume that the image distance is v cm.
Given that the magnification is m, we can write the equation as:
m = -v/16
Rearranging the equation, we get:
v = -16m
So the image distance is given by -16m.
Therefore, the image distance is -16m cm.
m = -v/u
where m is the magnification, v is the image distance, and u is the object distance.
In this case, the object distance is given as 16 cm, so u = 16 cm.
Let's assume that the image distance is v cm.
Given that the magnification is m, we can write the equation as:
m = -v/16
Rearranging the equation, we get:
v = -16m
So the image distance is given by -16m.
Therefore, the image distance is -16m cm.
