The Attempt at a Solution
Hello people, I'm having a problem understanding the section on this and the question I posted above is the very first question. My teacher said I can't use the formula Ln=(2n-1)lamda/4 or Ln= nlamda/2 . Could you please show me how to do this question with the formulas I listed above? Fast help would be appreciated. Thank you very much in advance.
