We investigated quasi-periodic pulsations (QPPs) in X-ray and extreme-ultraviolet (EUV)emissions during the X-class solar flare (SOL2022-03-30T). Two modes of quasi-periodic pulsations were detected. A longer quasi-periodicity of about 4 minutes was detected during theimpulsive phase of the flare, which can be interpreted as a manifestation of slow acousticwaves in the chromosphere. In addition, a shorter quasi-periodicity of approximately 2 minuteswas found throughout all evolutionary phases of the flare in the 94 Å channel. This featuremay be explained by a self-oscillatory regime of magnetic reconnection. Our results suggestthat the observed QPPs are associated with both wave dynamics and periodic modulation ofnon-thermal electron acceleration by repetitive magnetic reconnection.
