HEY MATE ..✌✌✌

To obtain a real and inverted image of same size we must use CONVEX LENS.

In a convex lens when object is held at 2f than the image is formed real and inverted.

We know than:

2f = 2×f

i.e 4 =2×f

f = 4/2 = 2 m

hence, The focal length is 2 m.

The lens is placed at a distance of 4 mfrom the candle.
