2016年8月10日 · What is the visible light spectrum? The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
Visible Light Spectrum Overview and Chart - ThoughtCo
2024年5月2日 · The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red).
Visible Spectrum - LIGHT, COLOUR & VISION
The diagram shows that wavelengths of light within the visible spectrum correspond with the different colours we see in the world. Notice that: The white arrows in the diagram represent the Sun emitting sunlight at every wavelength of the visible spectrum. The term white light is used when all colours of the visible spectrum are mixed together.

2008年7月29日 · Visible light. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colours of the rainbow. Each colour has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. Image acknowledgement: Delcreations ...
24.3: The Electromagnetic Spectrum - Physics LibreTexts
Visible light is the narrow segment of the electromagnetic spectrum to which the normal human eye responds. Visible light is produced by vibrations and rotations of atoms and molecules, as well as by electronic transitions within atoms and molecules.
