Calculating the wavelength and energy

Reference no: EM13112361

The blue color of the sky is due to the scattering of sunlight by the molecules in the air. The blue light has a frequency of about 7.5 x 10^14 Hz.
A. Calculate the wavelength, in nm, associated wth this radiation.

I believe the correct formula for this part is speed of light (299,792,458 m/s x 7.5 10^14 Hz).

B. Calculate the energy, in joules, of a single photon associated with this frequency.

I do not understand how to set this portion of the problem up.

C. Calculate the energy, in KJ, of 1 mole of these photons.

Unable to do because I do not understand how to do part B.
