except you can still arguably see things that don't reflect light, if you were anywhere near a black hole (let's imagine it has no accretion disk and thus isn't surrounded by a bunch of light) it'd be pretty obvious what with the bending of light and how it's a disk of pure blackness against the backdrop of stars.

And you know, light sources. They don't need to reflect any light.

But they still do. It might just be overpowered by the emitted light.

Does a candle really reflect light?

[-] stephen01king@lemmy.zip 6 points 2 months ago

Candle fire does reflect light, that's why it has a shadow.

[-] CrazyLikeGollum@lemmy.world 3 points 2 months ago

Yes. The flame is a cloud of gas and particulate heated to the point that it glows. It will reflect light. Just not a lot, and it's also emitting enough light to overpower any reflected light in most conditions.

And of course the candle itself reflects light.

It doesn't need to reflect any light though.

Yes, paraphene candle reflects light, unless you won't know that it's white

[-] lud@lemm.ee 2 points 2 months ago

I obviously mean the flame.
