We would be able to see with night-vision during the night.
Yes it will
If infrared didn't exist, many animals that rely on infrared sensing for hunting or navigating at night would need to find alternative methods. Additionally, infrared technology, such as night vision goggles and thermal imaging cameras, would not work, impacting various industries like military, security, and healthcare. Our understanding of the Universe through infrared astronomy would also be limited.
Yes, it would defiantly work, as the type of light is exactly the same.
I doubt they would be if they had the ability to see the colour yellow.
The best tool for finding a child lost in the woods at night is a forward-looking infrared (FLIR) device or system incorporated into a helicopter. All people emit infrared radiation, which is invisible but very close to the red end of the spectrum of visible radiation (light). The FLIR system has a camera on the outside of the helicopter which is sensitive to infrared wavelengths, and a TV-type monitor in the cockpit. Because the infrared is emitted instead of simply reflected, and because the strength of the emitted infrared radiation is proportional to the amount of heat the body emits, it is extremely easy to see people in the converted images. They appear completely white against a background of various shades of dark gray.
Butterflies live in flowers and trees during the night. How would I know that? I'm one of them.
it mostly fly during night but rairly during daytime
A PM tube doesn't operate in that wavelength. A PM tube detects light which is generated from a scintillator. The scintillators are typically designed to scintillate as a result of a reaction with ionizing radiation.
Because it sleeps during the night
i would say it is not good to exercise at night because if you do it will not allow you to sleep so it would be better to exercise during the day
Microwaves would have longer wavelengths than infrared rays.
Absolutely yes, if it were sensitive in the 9.7 micron band. According to Wien's law, the peak wavelength for cavity radiation at 298K is about 9.7 micrometers.
