What Is Non-Visible Light? The human eye can only see visible light, but light comes in many other "colors"—radio, infrared, ultraviolet, X-ray, and gamma-ray—that are invisible to the naked eye. ... On the other end of the spectrum there is X-ray light, which is too blue for humans to see.

Visible light has a wavelength that ranges from 380 nm – 750 nm on the electromagnetic spectrum while infrared light is just beyond it, ranging from 700 nm – 1 mm, the start of the non-visible portion of the spectrum. As a result, infrared cannot be seen except with special equipment like a security camera.

Infrared light, microwaves, television waves, and radio waves are invisible forms of electromagnetic radiation; their wavelengths are greater than that of visible light, and thus their energies are lower than that of visible light. FIGURE 5.2 The electromagnetic spectrum.

Light waves, however, are ripples in electric and magnetic fields—which is why they are also called electromagnetic waves. There is no fundamental difference between visible light and invisible light such as radio waves and X rays. They are all electromagnetic waves that differ in only one way: their wavelength.

The difference between visible exports and visible imports is known as Balance of Trade (BOT). Invisible goods are not recorded at ports and are not seen crossing the borders. Invisible trade involves the import and export of services rather than goods.

Difference between Luminous and Non-Luminous Objects Objects that can emit light energy by themselves are known as luminous objects. Objects that cannot emit light energy by themselves are known as non-luminous objects. These objects can cause the sensation of light. These objects do not cause the sensation of light.

The Visible Spectrum Visible light is the light that we can see, and thus is the only light detectable by the human eye. White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers.

As adjectives the difference between bright and dim is that bright is visually dazzling; luminous, lucent, clear, radiant; not dark while dim is not bright or colorful.

ultraviolet light is below violet light and invisible to the human eye. infrared light is above red on the spectrum and also invisible. ... These colors range from a deep violet to red and comprise the visible light spectrum. ultraviolet light is below violet light and invisible to the human eye.

The difference between Clear and Opaque. ... When used as adjectives, clear means transparent in colour, whereas opaque means neither reflecting nor emitting light. Clear is also adverb with the meaning: all the way.

As adjectives the difference between evident and visible is that evident is obviously true by simple observation while visible is able to be seen.

Infrared waves have less energy than visible light waves. Infrared waves are longer with more space between each high and low. Ultraviolet waves have more energy than visible light does. It's this energy that can hurt us.

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.

Light transmission capacity varies from object to object. Transparent objects allow all the light to pass through them, translucent ones allow partial light to pass, whereas opaque ones allow no light to pass through.

Visible light is electromagnetic radiation with wavelengths ranging from roughly 400 and 700 nanometers. In physics, a color is visible light with a specific wavelength. Black and white are not colors because they do not have specific wavelengths.

Red light is visible and is most effective for use on the surface of the skin. Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm. Infrared light is invisible and is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body.

The difference between X-rays and visible light rays is the energy level of the individual photons. ... Our eyes are sensitive to the particular wavelength of visible light, but not to the shorter wavelength of higher energy X-ray waves or the longer wavelength of the lower energy radio waves.
