resonance has high amplitude? why?  
Asked by spurthireddy1225 | 28 Dec, 2020, 08:41: PM
answered-by-expert Expert Answer
When waves are superimposed on one another in phase their amplitudes are getting added
together and the phenomenon of resosnace occurs. When amplitudes are added together in phase we get high amplitude
 
If the superimposed waves are not in phase , then they have random displacements of particle along the wave motion.
Some added displacements may have opposite dircetions , hence if they are added together we may get nil displacement or
minimum diesplacement.

Even if the added displacements are having smae direction, they may not have equal magnitude .
Hence we will not get maximum amplitude, when superimposed waves are not in phase
