Answer:
E) microwave, infrared, visible, ultraviolet
Explanation:
Electromagnetic waves are waves consisting of oscillations of electric and magnetic fields. These fields oscillate in a direction perpendicular to the direction of propagation of the wave, so they are called transverse waves. Electromagnetic waves are the only waves that can travel in a vacuum, since they don't need a medium to propagate.
Electromagnetic waves are classified into 7 different types, according to their different frequency. In order from lowest to highest frequency, we have:
Radio waves
Microwaves
Infrared
Visible light
Ultraviolet
X-rays
Gamma rays
Moreover, for an electromagnetic wave the energy carried is proportional to its frequency:
[tex]E=hf[/tex]
where h is the Planck constant and f is the frequency. Therefore, the list written above also corresponds to the list of waves from lowest to highest energy. so, the correct answer is
E) microwave, infrared, visible, ultraviolet
