the readings are equal to half lambda, you should subtract (192-36) and (356-192) and (516-356) you will get 156,164,160umm ppl in may 2012 papr phys 3b qstn 8b.... i dont know where to start the calculation from.....can someone show me the steps in how to do that part?
take the average which is 160, and the uncertainty which is +-4
now let's not forget it's lambda over 2, so lambda/2=160
lambda equals 320, uncertainty is +-8
