Calculate the wavelength of a photon having 3.26 x 10^-19 joules of energy

The energy of a photon is given by:

where h is the Planck constant and f is the photon frequency.
We know the energy of the photon, , so we can rearrange the equation to calculate the frequency of the photon:


And now we can use the following relationship between frequency f, wavelength  and speed of light c to find the wavelength of the photon:

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4

2. they have negligible mass.
