One type of electromagnetic radiation has a frequency of 107.1MHz,another type has wavelength of of 2.12x10^-10 m,and another ty
Andreas93 [3]

Each type of electromagnetic radiation and placed in order of increasing photon energy and increasing frequency

  • FM Radio waves < Visible light < X - rays
  • Order of increasing frequency.
  • FM Radio waves < Visible light < X - rays

This is further explained below.

<h3>What is electromagnetic radiation?</h3>

Parameters

Frequency =107 100 000 hertz

Wavelength, λ = c / ν => 2.8 m => 2.12 * 10-10 m

Energy = 3.97 * 10 -19 J/ photon.

Generally, the equation for Wavelength is  mathematically given as

λ = h c / E

Therefore

λ =6.626 * 10-34  * 3 * 108  / (3.97* 10 -19 J)

λ =5 * 10-7 m

In conclusion, This is considered to be part of the viewable area (green Increasing photon energy from lowest to highest.

  • FM Radio waves < Visible light < X - rays
  • Order of increasing frequency.
  • FM Radio waves < Visible light < X - rays
