which type of electromagnetic radiation can a healthy human eye detect?
475162
Visible light is a kind of electromagnetic radiation, it is a narrow part of the electromagnetic spectrum that is visible to the human eye. Light, like other types of electromagnetic radiation, exhibits characteristics of both waves and particles - this is referred to as the dual nature of light.

More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

Electromagnetic Radiation: The most familiar form of electromagnetic (EM) radiation is sunshine, which provides light and heat. Sunshine consists primarily of radiation in infrared (IR), visible, and ultraviolet (UV) frequencies.

The infrared has longer wavelengths (700 nm to 1 mm) than those of visible lights (390 nm to 700 nm). Note though that visible light is the only radiation that can be seen by the human eye. The ultraviolet is much more intense and has a shorter wavelength (400 nm to 10 nm) compared to visible light.

Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes. ... This broad range of wavelengths is known as the electromagnetic spectrum.

Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation.

Both are types of electromagnetic radiation only visible light is at a frequency that the human eye can detect while ultraviolet light is at a frequency that's just beyond what the human eye can detect. Since UVL has a higher frequency, that means it's at a greater energy state.
801659
The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.
146655
The higher frequencies of EM radiation, consisting of x-rays and gamma rays, are types of ionizing radiation. Lower frequency radiation, consisting of ultraviolet (UV), infrared (IR), microwave (MW), Radio Frequency (RF), and extremely low frequency (ELF) are types of non-ionizing radiation.

Visible light and X-Rays exist on the same spectrum of waves. They are both electromagnetic waves. The difference between the two is that the human eye can only see light between about 400–700 nm wavelength. X-Rays typically have a wavelength of about 0.01–10 nm.

The technology that is used in airport security scanners has the potential to be a skin cancer diagnostic tool, a scientist is claiming. The scanners use so-called terahertz radiation ("t-rays"), which has the ability to look through human skin and tissue. T-rays are considered non-ionizing, similar to visible light.

Cones are most sensitive to light at wavelengths around 420 nm. However, the lens and cornea of the human eye are increasingly absorptive to shorter wavelengths, and this sets the short wavelength limit of human-visible light to approximately 380 nm, which is therefore called 'ultraviolet' light.

Explanation: Electromagnetic waves with wavelengths greater than 750 nm are infrared light. They are not visible to human eyes, but we can feel them as heat on our skin.

You are here The entire rainbow of radiation observable to the human eye only makes up a tiny portion of the electromagnetic spectrum – about 0.0035 percent. This range of wavelengths is known as visible light.

Visible light is the white light the human eye can perceive. ... Infrared light has a high frequency and is ore energetic, thus the heat energy, while ultraviolet is a lower frequency or less energetic. The lower end of the spectrum also includes microwaves and radio waves.

Ultraviolet astronomy is also best done from space. Electromagnetic radiation with wavelengths between roughly 400 and 700 nm is called visible light because these are the waves that human vision can perceive. This is also the band of the electromagnetic spectrum that most readily reaches Earth's surface.
