Why can't humans see ultraviolet and infra-red colors when some animals can?

The reason we can't see it is because we cannot see the other spectrum of electro-magnetic radiation because our eyes are not equipped with the proper sensors to "sense" the other forms of electromagnetic radiation.
Electromagnetic radiation is all the rays that come from the Sun,
The are 7 types of this radiation.
Radio
Microwave
Infrared
Visible (ROYGBIV) Rainbow, Light
Ultraviolet
X-rays
Gamma rays
The only rays we as humans can see are the VISIBLE ones.
X-Rays and Gamma Rays don't get through the ozone layer, So don't panic. About the part with the animals seeing, I don't think they can either. The rays travel too fast to be caught on even the best cameras.

∙ 14y agoNot from you and not from the one who asks you. ^? Im unsure about infrared by there are certainly animals that see UV light, for examply sime flowers have special colouring that reflects UV light, invisible to most animals but not to bees.

∙ 13y agoOur eyes can detect the radiation only in visible region of the electromagnetic radiation. Some animals have capacity to detect ultraviolet or infra-red radiation. Adaptation and natural selection are very important for any species.

outside the limits of the range of wavelengths that the light-sensitive cells
on the retina of our eyes can detect.

∙ 15y agoAs in most cases in nature, animals, including humans, see what is important for their survival. So the spectrum of light that we see is based on the need to see certain colors. We have three types of receptors, called cones, that help us see the colors of the rainbow. There are some animals, like shrimp, that have up to 30 different cones so they can see very subtle changes in the colors of their food sources underwater. Bees, on the other hand, see ultraviolet rays, and many flowers reflect in the ultraviolet range, so they can attract the bees to where their pollen is.

Does white light contain ultraviolet and infrared light?
Not necessarily. It could, but as humans cannot perceive these colors, and white is based off of our perception of a color containing red, blue, and green, ultraviolet and infrared are not necessary to create "white".
What are three forms of radiation that humans cannot see?
ultraviolet, infrared, x-rays
Type of radiant energy is invisible to humans?
-- radio -- heat -- infrared -- ultraviolet -- microwave -- X-rays -- gamma rays -- cosmic rays
Why animal can see infrared and ultraviolet rays?
Quite simply, because there are individual differences between species. In this case, the range of the electromagnetic waves they can see is a little larger for some animals. I don't think that ALL animals, or even all animals with eyes, can see a larger range of radiation than humans.
Can animals or humans see infrared radiation?
Humans can't see that. Some animals have a different range of radiations they can see. One interesting case is certain snakes, which have a special organ to sense heat radiation (i.e., infrared radiation). This helps them find their prey.
Does white light contain ultraviolet and infrared light?
Not necessarily. It could, but as humans cannot perceive these colors, and white is based off of our perception of a color containing red, blue, and green, ultraviolet and infrared are not necessary to create "white".
Why do graphs help explain why humans cannot see colors that fall in the ultraviolet or infrared part of the electromagnetic spectrum?
Because we can't see the colors on the spectrum so we have to use a graphto show the colors.
Which colour can not be seen by a human?
Humans do not see the infrared or ultraviolet forms of light.
What are three forms of radiation that humans cannot see?
ultraviolet, infrared, x-rays
What is Ultraviolet lights?
Ultraviolet light (UV light) is light of shorter wavelength than the visible spectrum. Many insects, like bees, see mostly UV light so they can find plants with nectar. Sunlight contains UV light and can tan but also damage your skin if you stay outside too long on a sunny day.Answer:Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher frequency and infrared is lower.Note: Higher frequencies are shorter wavelengths and lower frequencies are longer wavelengths.Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher and infrared is lower
What color are sun rays?
infrared, red, orange, yellow, green, blue, purple, ultraviolet. The sun has a lot of different colors in it, all you have to do is take a prism, and put it in front of a beam of sunlight, to see that the white light coming from the sun has many parts. Just realize humans cannot see infrared or ultraviolet.
What kinds of environmental stimuli are some animals capable of sensing that humans cannot sense?
Some would be infrared or ultraviolet light or subsonic sounds. We can't see these nor can we hear them.
Can humans see all light?
NO, HUMANS CAN SEE LIGHT BETWEEN THE WAVELENTHS OF VIOLET AND RED. HUMANS CANNOT SEE ULTRAVIOLET OR INFRARED LIGHT.
Is ultraviolet light invisible?
Humans do not have the ability to see ultraviolet light. We are only able to see from red to violet, not ultravioltet (above violet) or infrared (below red).
Which light can humans see?
Humans can see light all the way from red to violet, but not morethan red (infrared) nor more than violet (ultraviolet).
Type of radiant energy is invisible to humans?
-- radio -- heat -- infrared -- ultraviolet -- microwave -- X-rays -- gamma rays -- cosmic rays
Why animal can see infrared and ultraviolet rays?
Quite simply, because there are individual differences between species. In this case, the range of the electromagnetic waves they can see is a little larger for some animals. I don't think that ALL animals, or even all animals with eyes, can see a larger range of radiation than humans.
