Consider two black bodies A and B having equal surface areas. On the surface of A, ' n ' photons of frequency ' f ' are incident perpendicularly in a time ' t '. On the surface of B, ' 2n ' photons of frequency ' 3f ' are incident perpendicularly in a time ' 4t '. The ratio of average intensity of radiation on surface A to that on surface B is
