Question

Microwave radiation has a wavelength on the order of 1.0 cm. Calculate the frequency and the energy of a single photon of this radiation. Calculate the energy of an Acogadro's number of photons of this radiation

Answer 1

We have 1 piece of information here: Wavelength of 1.0 cm. We want the Energy of a single photon and there is an equation that solves for this. \[E = \frac{ hc }{ \lambda } \] that equation should be in your text book. Avogadro's number is one you should memorize and because it is simply a number, you can multiple it by the amount of energy you get to get the avogadros number of photons of energy
