摘      要：In this study,the optical properties of a renormalization group improved(RGI)Schwarzschild black hole(BH)are investigated in a plasma *** with the equations of motion in a plasma medium,we aim to present the modifications in the shadow radius of the RGI *** this end,we compute the deflection angle of light in the weak gravity regime for uniform and non-uniform plasma ***,owing to the plasma media,we discover that the equations of motion for light obtained from the radiating and infalling/rest gas have to be ***,in turn,changes and modifies the expression for the intensity observed far away from the ***,we obtain the shadow images for the RGI BH for different plasma *** quantum effects change the background geometry,such effects are minimal,and practically detecting these effects using the current technology based on supermassive BH shadows is *** parameterΩencodes the quantum effects,and in principle,one expects such quantum effects to play significant roles only for very small ***,the effects of plasma media can play an important role in the optical appearance of BHs,as they affect and modify the equations of motion.
