    Note:
    1. If possible, find the rough focal length of the convex lens.
    2. Initially, keep the distance Between the lens and object around 2f cm and then go ahead and remove the parallax and take readings.
    3. For further readings, increase the distance between the lens and object by 1 cm or 2 cm and take readings.
    4. For removing parallax error, move your head around and not your eyes. Also keep your eyes at 30cm distance from tips while removing parallax.

      Once calculate the value of f 😂
      As for f=uv/u-v
      At 2 f u=v
      So u-v=0
      And f=uv/0 which is approx to infinity
      So how is he getting 15
