Then different aspects of the electromagnetic spectrum are as follows:
Microwave- this (fun fact-microwave is an onomatopoeia) is the second slowest wave, with a very slight difference than radio waves in frequency and speed. This is invisible to the naked eye.
Infrared- this wave, while invisible to the naked eyes, is used in the technology of thermal seeking goggles. The red light that emits from animals is actually infrared light. This has a higher frequency and speed, at 10-^5
Visible light- visible light is only slightly higher than infrared light in frequency in energy. At 10-^6, it brings colour and light into the world
Violet light- Violet light is substantially faster and higher in frequency than visible light. It has started the spectrum's spike in energy.
X-Ray- this wave has a high frequency and energy level. This type of wave has a radiation type of 10-^10, even larger than violet light. It is used to inspect bones and other foreign objects in the body.
Gamma Ray- with a radiation type of 10-^12, this has the highest energy level of all of the waves.
