Here's a breakdown:
* Visible light spectrum: This is the range of electromagnetic radiation that humans can see. It's often represented as a rainbow, with each color having a specific wavelength.
* Red light: Has the longest wavelength in the visible spectrum, ranging from approximately 620 to 750 nanometers (nm).
* Other colors: As you move towards the blue end of the spectrum, the wavelengths get shorter:
* Orange: Around 590 to 620 nm
* Yellow: Around 570 to 590 nm
* Green: Around 495 to 570 nm
* Blue: Around 450 to 495 nm
* Indigo: Around 430 to 450 nm
* Violet: Around 380 to 430 nm
Therefore, the wavelengths closest to red light are those of orange light, which are slightly shorter.
