wavelength from 0.9 to 7.0 so in a way you can say that the wavethength is short.First, a basic fact: light in the SWIR band is not visible to the human eye. The visible spectrum extends from wavelengths of 0.4 microns (blue, nearly ultraviolet to the eye) to 0.7 microns (deep red). Wavelengths longer than visible wavelengths can only be seen by dedicated sensors, such as InGaAs. But, although light in the shortwave infrared region is not visible to the eye, this light interacts with objects in a similar manner as visible wavelengths. That is, SWIR light is reflective light; it bounces off of objects much like visible light. As a result of its refelctive nature, SWIR light has shadows and contrast in its imagery. Images from an InGaAscameraare comparable to visible images in resolution and detail; however, SWIR images are not in color. This makes objects easily recognizeable and yields one of the tactical advantages of the SWIR, namely, object or individual identification.
Both a wave with long wavelength and a wave with short wavelength can have a lot of energy, or little energy.Specifically in the case of electromagnetic waves, a short wavelength corresponds to high energy - but this is only the energy PER PHOTON. But note that each of such waves usually consists of a lot of photons.
There is a simple answer and a complicated answer. The simple anser is, "Neither", the complicated answer is , "It depends."
The wavelength of infrared light is too long for humans to see.
Short wavelength waves bend less than long wavelength waves when they pass through a medium because they have higher frequencies and shorter distances between wave crests. This phenomenon is known as refraction.
Infrared light has wavelengths that are too long for us to see. This type of light is often used in night-vision technology and can be detected as heat by certain animals such as snakes and pit vipers.

Scattering of light
The color of visible light with the longest wavelength is red; the color with the shortest is violet. So "ROY G. BIV" lists the colors from long to short wavelength. Just to confuse you, we'll also mention that it lists them from lowest to highest frequency.
The wavelength of infrared light is too long for humans to see.
Cone opsins are genes that encode for proteins responsible for color vision in cone cells of the retina. Humans have three cone opsin genes - long-wavelength (red), middle-wavelength (green), and short-wavelength (blue) - which allow us to perceive a wide range of colors. Mutations in cone opsin genes can lead to color vision deficiencies or color blindness.
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
Short wavelength waves bend less than long wavelength waves when they pass through a medium because they have higher frequencies and shorter distances between wave crests. This phenomenon is known as refraction.
The wavelengths of electromagnetic radiation extend from any long wavelength, withno upper limit no matter how long, continuously through all possible wavelengths, withno gaps, down to any short wavelength, with no lower limit no matter how short.
