Were early homo sapiens able to see the infrared spectrum at night?
AndrewSavagefb5608
No primate can see infrared at any time. There are very few creatures that can see infrared as it cannot be focused with a biological produced lens (due to the water that will be present, which absorbs infrared), so a type of eye based on the pinhole camera must be used by these few creatures.
The only creatures that I am aware of that can see infrared are the snakes known as pit vipers. They are called pit vipers because their pair of infrared "eyes" look like tiny pits in their face.

How did the discovery of the use of the fire affect early hominds?
The discovery of fire allowed early hominids to stay warm, cook food, protect themselves from predators, and extend their activities into the night. It also led to social bonding and the development of more complex societies.
What is the time period of homo habilis?
Homo habilis lived approximately 2.1 to 1.5 million years ago during the Early Pleistocene epoch.
What are the four different uses and how the early humans benefited it?
Early humans used fire for warmth, cooking, protection from predators, and for light. They benefited by being able to stay warm in colder climates, cook food which made it easier to digest and obtain more nutrients, fend off predators, and extend their productivity and social activity into the night with the help of light.
What do homo habilis do all day and night?
eat
What was cro-magnon community size?
The Cro-Magnon community size is estimated to have been fairly small, with around 20-30 individuals living together. They likely lived in small bands or extended family groups, allowing for close social interactions and cooperation for hunting and gathering.
What do night vision cameras use?
infrared spectrum
Which band of em spectrum used in night sight?
infrared
If you are using night-vision goggles what part of the spectrum are detecting?
infrared rays
If you are using night-vision goggles what part of spectrum are you detecting?
infrared rays
If you are using night-vision goggles what part of the spectrum are you detecting?

Electromagnetic spectrum infrared radiation used for?
Communications Remote control (TVs etc) Night vision goggles
Is night vision and infrared vision the same?
No, night vision is the ability to see in low light condition and infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging, are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.
What sensors primarily operate in the EM spectrum just below the range of visible light?
Sensors that primarily operate in the electromagnetic spectrum just below the range of visible light include infrared (IR) sensors. These sensors detect and measure infrared radiation, which has longer wavelengths than visible light. They are commonly used in applications such as night vision devices, remote temperature sensing, and proximity detection.

Are 'infrared light' and 'night vision' the same thing?
NO Infrared light show the heat of the body
What is the type of remote sensing imagery best suited to use at night?
Thermal infrared.
How is infrared radiation used for?
Infrared is heat. When you feel the warmth of a space heater, you feel the effect of infrared radiation. The other uses are motion detection (infrared sensor) and night-vision (live animals have a heat signature, a blurred image, against a colder background at night). ======================
