Answer» A student was asked by his teacher to find the image distance for various object distance in case of a given convex lens. He performed the experiment with all precautions and noted down his observations in the following table: $\begin{matrix} S . N o & O j b e c t d i s t a n c e (c m) & I m a g e d i s t a n c e (c m) 1 & 60 & 15 2 & 48 & 16 3 & 36 & 21 4 & 24 & 24 5 & 18 & 36 6 & 16 & 48 \end{matrix}$ After checking the observations table the teacher pointed out that there is a mistake in recording the image distance in one of the observations. Find the serial number of the observations having faulty image distance.
