Frequency of light = the number of times in a second the light wave (electric field in it) oscillates to and fro in one second. Units are : Hz
Intensity of light = power in light rays falling on a unit surface area. Power is energy / sec. Units are : J /sec /m^2
Intensity is directly proportional to the square of the frequency.
