Throughout  history,  launching  satellites  equipped  with  cutting-edge  instruments  has consistently expanded our understanding of solar physics.  Launch of the Solar Orbiter is not an exception and since its launch already there have been a lot  of new discoveries specifically focused on small scales such as for example campfires or picojets.  In  this  talk,  I  will  delve  into  two  recent  studies  that  we've  done  utilizing  data  from  the  High- Resolution  Imager  in  the  Extreme  Ultraviolet  telescope  (HRIEUV)  onboard  Solar  Orbiter  and  discuss how those works fit and contribute into our current understanding of the waves.  The first study focuses on the detection of high-frequency decayless kink oscillations in small loops  in  a  quiet  region  of  the  Sun.  Due  to  the  unprecedented  imaging  cadence  of  the  corona,  we  were  able to detect oscillations with periods that are shorter than the previously observed range, hinting  at a significant energy budget associated with these phenomena. The  second  one  is  related  to  detection  of  torsional Alfvén  waves  in  a  fan-spine  topology.  In  this  work  we  combine  the  observations  from  several  instruments  onboard  Solar  Orbiter,  namely  mentioned already HRIEUV, PHI and SPICE. This is the first time we see signatures of propagating  torsional motion in corona as observed by the three instruments onboard Solar Orbiter.
