That's called visible light.
The electromagnetic spectrum is a range of all possible frequencies of electromagnetic radiation. Light, the waves commonly referred to, falls within a specific region of this spectrum, primarily in the visible spectrum. This includes wavelengths of light that our eyes can detect, ranging from approximately 400-700 nanometers.
We detect electromagnetic radiation in a narrow band of frequencies that we call "visible light" with our eyes. We can feel a broader spectrum of electromagnetic radiation that we call "heat". (There are some overlaps.) We can build tools that detect ANY frequency of electromagnetic radiation, and display that in any format we select.
The Arecibo telescope can detect radio waves in the electromagnetic spectrum. It operates at radio frequencies between 300 MHz to 10 GHz, allowing it to study objects such as pulsars, galaxies, and the Earth's atmosphere.
I suppose you mean the visible spectrum, only a small part of the entire electromagnetic spectrum. The visible spectrum is basically all of the colors the human eye can detect.
1100nm is in the near-infrared region of the electromagnetic spectrum. This region is just beyond the visible spectrum of light that the human eye can detect.
To detect different wavelengths of the electromagnetic spectrum.
A human eye can detect electromagnetic radiation in the visible light spectrum, which ranges from about 400 to 700 nanometers in wavelength. This encompasses colors ranging from violet to red.
They can detect both visible light and infrared radiation.
The sun emits a wide range of frequencies across the electromagnetic spectrum, but human eyes can only detect a small portion known as visible light. In addition to visible light, the sun also emits ultraviolet, infrared, and radio frequencies, among others.
We generate and detect electromagnetic waves that have frequenciesbetween 15 KHz and 300 GHz for a huge number of different purposes.In addition to the ones we're able to generate, other electromagnetic waves occurin nature, with frequencies up to 3,000,000,000,000,000,000 GHz.
The portion of the electromagnetic spectrum that the human eye can detect is known as visible light. This range of wavelengths is approximately between 400 to 700 nanometers. Outside of this range, humans are unable to perceive the electromagnetic radiation as light.
