How are we really supposed to pronounce the word "infrared"?

Question

I've been watching these astronomy shows on youtube, and they always say infrared like the word "impaired"; however whenever I here people talking about night vision or rifle sights, they always say infra-red... the "red" part separate, like it's two words. hat's the proper way?

Answer 1

Infra-red.

Answer 2

If someone pronounces it to rhyme with "impaired," then you should be very skeptical of anything they say. Nobody who's ever actually heard the word spoken by a scientist would make that mistake.



It's infra-red.

Answer 3

It is two words.



like infra + red.
