# Problem: One type of electromagnetic radiation has a frequency of 107.1 MHz, another type has a wavelength of 2.12 x 10-10 m, and another type of electromagnetic radiation has photons with energy equal to 3.97 x 10-19 J/photon. Identify each type of electromagnetic radiation and place them in order of increasing photon energy and increasing frequency.

We are given different types of values for each of the electromagnetic waves but we are asked of place them in order of increasing photon energy and increasing frequency. So we can't really compare them directly so we have to solve for all frequencies and energy.

Also, the type of electromagnetic radiation is based on wavelength, so we have to calculate for that too.

To better organize our values well make use of a table shown below where we name the waves as A, B, and C in the order that they were introduced in the problem.
