An object is placed 60 cm from a convex lens with a focal length of 15 cm. Calculate the image position and its nature.
💡 Hint: Use the lens formula carefully by substituting focal length and object distance.
If the object distance is changed to 5 cm while using the same lens of focal length 12 cm, where is the image, and what is its nature?
💡 Hint: Find 'v' using the lens formula, mind the signs for distances.
