Light Spectrum

[Yajing Feng 2J]

Hi!

I have a question regarding the ranges of the light spectrum. For example, microwaves are from 30mm to 1mm and infrared is from 1mm to 700nm. So is a radiation has a wavelength of exactly 1mm, what type of radiation would this be?

[Divya Hebbar]

I believe infrared light has a wavelength of 1 mm!

Hi! I just looked your question up and a majority of the answers say that if a wavelength is exactly 1mm, then it would be a microwave.

According to this site, that wavelength would apply to microwaves.

I'm not sure, but I don't think wavelengths are ever a perfect whole number so I'm not sure it matters practically. There is always some decimal to it, so if the wavelength were slightly higher than 1 mm then it'd be a microwave and if it were slightly below 1 mm, it'd be infra-red.

Is the wavelength of 600-700nm considered visible light that is closer/comparable to the wavelength of infrared radiation?

[Arshaun Faraji 2H]

This wavelength would be considered a microwave. 1nm falls into the range of microwaves on most websites i found.
