EASY
Is the complete range of electromagnetic waves arranged by increasing frequency and decreasing wavelength.
Electromagnetic Spectrum
Waves that have wavelength and frequency that necessarily travel at the speed of light.
Electromagnetic Spectrum
Has the longest wavelength.
Radio waves
Has the Highest frequency.
Gamma rays
Has the highest Energy.
Gamma rays
This region came from the word "infra" and infra means below red light.
Infrared
Only part of EM spectrum visible to the human eye.
Visible Light
The uses of this region is medical X-ray imaging and airport scanners.
X-rays
Clinics (like Belo Medical Group) uses UV lamps or UV-based devices for skin treatments.
Ultraviolet
The wavelength of this region is shorter than Radio waves.
Microwave
