coefficient: they balance the chemical equation you have to make sure the number is as small as it can. It is also used to convert different compounds to compounds or quantities to quantities.
Good afternoon,
Infrared light wavelengths = 1,000 nm - 750 nm
Visible light wavelengths = 750 nm - 400 nm
UV (Ultraviolet) light wavelengths = 400 nm - 10nm
So, the correct order is Infrared - Visible - Ultraviolet
I hope this has satisfied you, and if you need anymore help, feel free to ask.
Have a good afternoon!
