Identifying the Visible Light Spectrum

1. Understanding the Electromagnetic Spectrum: The electromagnetic spectrum encompasses all types of electromagnetic radiation, arranged according to their wavelengths and frequencies.

2. Categories of Electromagnetic Radiation:

   • Gamma Rays: Have very short wavelengths and high frequencies; they are not visible to the human eye.
   • Microwaves: Have longer wavelengths than visible light and are also invisible to humans.
   • Infrared Waves: These waves have longer wavelengths than visible light and are detectable as heat but not visible.

3. Visible Light: This is the portion of the electromagnetic spectrum that can be seen by the human eye. It consists of wavelengths that range from approximately 400 nm (violet) to about 700 nm (red).

Final Answer

The only member of the electromagnetic spectrum that we can see is A) visible light.
