The range of electromagnetic waves that the human eye can detect is from approximately 400 to 700 nanometers in wavelength, corresponding to the colors of visible light ranging from violet to red. This range is often referred to as the visible spectrum.
Electromagnetic waves or radiation. "Light," however, generally refers to that portion of the EM spectrum that our eyes can detect.
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.
Our eyes are not sensitive to infrared waves because the photoreceptors in our eyes are designed to detect visible light, which has a shorter wavelength. Infrared waves have longer wavelengths than visible light, so they are not detected by our eyes.
Light is ONE SMALL RANGE of the electromagnetic spectrum. In other words, electromagnetic waves within a relatively small range of frequencies - the frequencies that we are adapted to seeing with our eyes - is called "visible light", or simply "light".
Nothing, apart from the fact that your eyes are only capable of seing "visible light" , ie within a certain wavelegth (couple hundred nanometres). All electromagneic waves are the same, save their wavelengths which range from gamma rays (shortest) to radio waves (longest, couple metres long). However, waves above Microwaves (X-rays, gamma rays) contain enough energy per photon to ionize electrons (remove them from their atoms). This can cause chemical bonds to break, which is why X-ray and gamma ray radiation can be dangerous.
Visible light - electromagnetic waves in the frequency range 430 to 770 teraHz.
The range of electromagnetic waves that human eyes can detect is known as the visible spectrum, which includes wavelengths from approximately 400 to 700 nanometers. These wavelengths represent the colors of the rainbow, from violet to red. Beyond this range are ultraviolet and infrared waves, which are invisible to the human eye.

That's called visible light.

Those in the range of spectral wavelengths labeled "visible light".
Your eyes can detect visible light, which is a form of electromagnetic radiation that falls within a specific range of wavelengths. This is why your eyes are sensitive to colors and brightness levels in the environment.
Our eyes are not sensitive to infrared waves because the photoreceptors in our eyes are designed to detect visible light, which has a shorter wavelength. Infrared waves have longer wavelengths than visible light, so they are not detected by our eyes.
Mainly because that's what they are. Exactly the same physical phenomenon as radio, microwave, heat radiation, ultraviolet, X-rays, and gamma rays, but with wavelengths in the narrow range that your eyes can detect.
Light is ONE SMALL RANGE of the electromagnetic spectrum. In other words, electromagnetic waves within a relatively small range of frequencies - the frequencies that we are adapted to seeing with our eyes - is called "visible light", or simply "light".
Visible light consists of the band of wavelengths to which the structure of the human eye is sensitive. Radiation outside of that band may enter the eye, but there's nothing in there that responds to it, so the brain remains unaware of it.
Visible light waves are the electromagnetic waves which are detected by the human eye. They make up only a small part of the electromagnetic spectrum. So, visible light is any light in which the human eye can detect.
