In this article, we calculate the deflection angle of tidal charged blackhole (TCBH) in weak field limits. First we obtain the Gaussian opticalcurvature and then apply the Gauss-Bonnet theorem on it. With the help ofGibbons-Werner method, we are able to calculate the light's deflection angle byTCBH in weak field limits. After calculating the deflection angle of light, wecheck the graphical behavior of TCBH. Moreover, we further find the light'sdeflection angle in the presence of plasma medium and also check the graphicalbehavior in the presence of plasma medium. Moreover, we investigate the shadowof TCBH. For calculating the shadow, we first find the null geodesics aroundthe TCBH and then find its shadow radius. We also obtain TCBH's shadow in theplasma medium. Hence, we discuss the shadow of the TCBH using the $M87^{*}$parameters announced by the Event Horizon Telescope.
