gamma rays have the highest penetration power, they have the highest frequency.

Look, Energy is proportional to frequency and inversely proportional to wavelength.So, Gamma ray has both parameters in favour as frequency is inversely proportional to wavelength. So, E=hvHence,Gamma ray has highest energy and m,ore penetrating power.Moreover it is not a particle ( no question arises regarding charge) and is a wave.Hence it has most pronounced penetrating effect.

gamma rays have d highest penetrating power..due to high speed n small mass..n it's observed that....it can penetrate through a lead sheet of 150mm thickness...(practically observed)(highest)
