HI, At first u have to determine the wall wheather it was glass,iron,wood.....etc < for example if the wall was made up of glass light will pass also but if it was made of iron radio waves won't pass through it> anyway i think u mean the normal wall which is found in our houses made up of cement the answer is Radio waves are much bigger than light waves,and radio waves are bigger than the size of atoms in a wall, that is why they go through, while light is a small wave and cannot get through the wall.
