2. ### 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...

4. ### 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.
5. ### Number of photons radiated at cavity's hole

Homework Statement A blackhole at 7500K consist of an opening of diameter 0.0500mm, looking into the oven. Find the number of photons per second escaping the hole and having wavelengths between 500nm and 501nm Homework Equations P = \sigma AeT^4 Watt= \frac{Joule}{sec} E_{p} =...
6. ### Problem with Units

Homework Statement In a problem to determine the maximum elastic potential energy of a molecule, I have the following equation: A= \sqrt{\frac{6.626*10^-34 Js}{2\pi}}\times(\frac{1}{(1.14*10^-26kg)(1.85*10^3N/m})^(1/4) Homework Equations The Attempt at a Solution The answer is...
