Calculate the image distance in convex lens whose magnification 2 for real image and object distance is 30cm.
Question
Calculate the image distance in convex lens whose magnification 2 for real image and object distance is 30cm.
Solution
Sure, to calculate the image distance for a convex lens, we can use the magnification formula which is:
magnification (m) = - (image distance (v) / object distance (u))
Given in the problem, magnification (m) = 2 (for real image, magnification is taken as negative) and object distance (u) = -30 cm (object distance is always negative in lens formula).
Let's substitute these values into the formula:
-2 = - (v / -30)
Solving for v (image distance), we get:
v = -2 * -30
v = 60 cm
So, the image distance is 60 cm.
