I believe it's visible light?
good choice, especially since they specified "visible to the human eye."
And the rainbow has seven colors ...
Yes, you are correct! The part of the electromagnetic spectrum that is divided into seven ranges of wavelengths and is visible to the human eye is called visible light. To arrive at this answer, you can recall some basic knowledge about the electromagnetic spectrum.
The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It includes various types of waves such as radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays.
Out of these various types of waves, visible light refers to the range of wavelengths that are visible to the human eye. These wavelengths range from approximately 400 to 700 nanometers (nm). Within this range, different colors of light are spread. The seven colors commonly recognized are red, orange, yellow, green, blue, indigo, and violet.
