Infrared is longer.
because light used to see an object must have a wavelength
The Kestrel can see into the Ultraviolet Spectrum. A human eye can see between 400nm - 700nm ( Visual Wavelengths. ) It is also correct to describe the human eye as being able to see between 4,000 - 7,000 Ångströms; The Ångström is simply another unit of measurement, like nm which = nanometers, on the Electromagnetic Spectrum. The smaller the number, as in 4,000 Ångströms, means that the wavelength is shorter, thus the electromagnetic radiation is of higher energy. As opposed to longer wavelengths such 7,000 Ångströms, which is closer to the Infrared. The Kestrel can image wavelenths as short as 3,000 Ångströms, or in correct notation, 3 x 10-7½
Wavelength lambda and frequency f are connected by the speed c of the medium. c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f
Radio telescopes allow us to see things that can't be seen in visible light. And vice versa, optical telescopes can show things that are not visible in radio telescopes. So, the information from both kinds of telescopes really complements each other.
The usual term is "collapse". This happens when the gas and radiation pressure, or degenerate pressure, is no longer enough to counteract gravity.
Infrared radiation.
It is electromagnetic radiation whose wavelength is longer than that of visible light.
Warm bodies emit infrared radiation.
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).
I have no clue Laugh out loud
Assuming you mean other electromagnetic waves: that would be infrared radiation, microwaves, and radio waves.
It becomes longer
Infrared radiation.
Deep dark red is the visible light with the longest wavelength. Violet is the visible light with the shortest wavelength.
Infrared radiation is not visible. Its wavelength is longer than red.
Because that's the name we have given to the electromagnetic radiation at the end of the spectrum with the longest waves.
