JEE Main 2012 Physics question
This question has Statement 1and Statement 2. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement 1: In the resonance tube experiment, if the tuning fork is replaced by another identical turning fork but with its arm having been filled, the length of the air column should be increased to obtain resonance again. Statement 2: On filling the arms, the frequency of a tuning fork increases.
Answer: (3)
Solution
Filing the prongs removes mass, so the frequency increases — Statement 2 is true. Higher frequency means
