A student is performing an experiment to determine focal length of a convex lens by using lens formula i.e., by no parallax method. The examiner gives some instructions to the student. The student responds to each instruction as per her understanding of the experiment.
State whether the student's response is correct or incorrect. Give a reason for your answer.
EXAMINER: Plot a graph of $(1/v)$ against $(1/u)$.
STUDENT takes $(1/v)$ on Y axis and $(1/u)$ on X axis.
Answer
Answer
AICorrect. In a graph of one quantity "against" another, the second quantity ($1/u$) goes on the X axis and the first ($1/v$) on the Y axis; the straight line then cuts the Y axis at $1/f$.
