Expert Answer:

Intensity of light is the number of photons incident on a surface and is measured in terms of energy of photons.
The intensity-wavelength graph gives the frequency distribution of emitted radiation.At a given temperature, intensity of light increases with decrease of wavelength since energy is inversely proportional to wavelength and then it reaches a maximum and then starts decreasing with further decrease of wavelength.
