This work explores various manifestations of bumblebee gravity within themetric-affine formalism. We investigate the impact of the Lorentz violationparameter, denoted as $X$, on the modification of the Hawking temperature. Ourcalculations reveal that as $X$ increases, the values of the Hawkingtemperature attenuate. To examine the behavior of massless scalarperturbations, specifically the quasinormal modes, we employ the WKB method.The transmission and reflection coefficients are determined through ourcalculations. The outcomes indicate that a stronger Lorentz-violating parameterresults in slower damping oscillations of gravitational waves. To comprehendthe influence of the quasinormal spectrum on time-dependent scatteringphenomena, we present a detailed analysis of scalar perturbations in thetime-domain solution. Additionally, we conduct an investigation on shadows,revealing that larger values of $X$ correspond to larger shadow radii.Furthermore, we constrain the magnitude of the shadow radii using the EHThorizon-scale image of $Sgr A^*$. Finally, we calculate both the time delay andthe deflection angle.
