Photon Density In A Light Beam

Sunlight falling vertically on a surface at the sea level has an intensity of 1600Wm^(-2) .Assuming 100% of the incident light is absorbed,the radiation pressure on the surface is

In a photoelectric experiment, the wavelength of the incident light is decreased from 6000A to 4000A . While the intensity of radiations remains the same,

In the photoelectric effect experiment, if f is the frequency of radiation incident on the metal surface and I is the intensity of the intensity radiations, then match the following columns:
