Question 6

Two microcantilevers, X X\,X and YYY, in an atomic force microscope oscillate with simple harmonic motion. The time period of cantilever X X\,X is 0.45 s and the time period of cantilever Y Y\,Y is 0.40 s.

The two cantilevers are released in phase.

What is the number of completed oscillations of cantilever Y Y\,Y before the two cantilevers are next in phase?
