what is the hotest part of the rainbow

[squarebear]

It's just a display of light and doesn't have a temperature.

[R1Geezer]

definately the red bit, I mean that blue is obviously bl00dy freezing.

[Teddio]

The region nearest the ground is likely to be warmest as the air temperature usually decreases with altitude.

[squarebear]

But it's just a light display. How could it have temperature?

Unless I'm very much mistaken.

[R1Geezer]

depends what is meant by rainbow, the actual bow is light formed from the sun shined through raindrops and as such is a light show, massless and therefore temperature less as squarbear says. Perhaps the questioner means the arc of raindrops being utilised in this way, in that case I'd say definately the red bits, err know sorry the bit's nearest the big yellow alligator, err sorry croc of gold err even the ground as teddio suggests.

rosemary please be more specific!

wtf? isnt a rainbow just refracted light? therefore having no temperature. and since light has no temperature there is no hottest part or coldest for that matter. i could be wrong though lol.

Blue/violet light is formed from hotter i.e. more energetic photons than red light. These do have mass, but not rest mass.

somewhere in the range -80C to +80C
