A convex lens forms a real and inverted image of a needle at a distance of 50 cm from it. Where is the needle placed in front of the convex lens if the image is equal to the size of the object? Also, find the power of the lens.
Given, a convex lens.
Image distance, v = + 50 cm [v is positive for real image]
As the real image is of the same size as that of the object, so
Object distance,
Now, using th lens formula,
we have,
Power of the convex lens,
