    Number of photons radiated at cavity's hole

    Thank you for your suggestions. I have verfied that the constant that I used is probably correct. Moreover, the limit of integration that I derived are based on the wavelengths expresed in nm, as you can see in my last post. Nevertheless, I carried out the calculation again and came up...

    Number of photons radiated at cavity's hole

    Then, why does the problem states a radius for the cavity"s hole. Plank's law does not specify a specific area for the radia tion intensity.
