No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

I'd think the answer is yes due to the lack of that type of radiation, but I haven't noticed a significant difference in my experience.

(I did google, but I couldn't find any answers to this)

You should look for semi-reflective or tinted glass if you want it to not let warmth pass in to your home. (And if you have double glasses, only the external one should be treated.)

The UV-blocking glasses will warm you less, but as you noticed, not enough to make a sensible difference. They add absorption of a very small band of light that isn't the most intense on Sun-light and is also absorbed by the atmosphere.

Not sure about how it feels on the skin, but here's a good explanation of how Low-E glass coatings keep homes cooler in the summer

It definitely heats your DNA less!

[–] [email protected] 4 points 5 hours ago

Slightly. Most of solar energy comes in as visible light, so any visible light that gets reflected won't contribute

[–] [email protected] 10 points 5 hours ago (3 children)

No. The UV light is on the other side of the rainbow from the light that makes you feel warm: Infrared.

[–] [email protected] 5 points 1 hour ago* (last edited 1 hour ago)

That's false. You can literally not only feel heat from, but you can in fact set things on fire with, a completely monochromatic green laser with a wavelength exactly in the middle of the visible spectrum. No infrared, no ultraviolet. Lots of heat transfer. You could do it with an ultraviolet laser too if you were careful enough and could get around ultraviolet's tendency to destroy molecular bonds completely before they even have a chance to burn chemically. It's not just lasers either, any light source is going to deposit energy in the form of heat on anything that light touches. Any light contains a large amount of energy and some of it will get absorbed by anything it interacts with, and that's still true whether it's infrared, ultraviolet, somewhere in between, or all the above.

Infrared has a special relationship with heat, yes, because of the distribution of blackbody radiation, but "No" is absolutely the wrong answer here. The right answer is "Yes, but... it's complicated".

This is correct but also glass blocks both ends of the spectrum. Really just visible light goes through glass. You get some near IR passthrough but not much.

[–] [email protected] 2 points 5 hours ago

There’s glass that doesn’t block UV frequencies—like the glass used in tanning booths, UV lights, and UV cameras.

[–] [email protected] 17 points 5 hours ago* (last edited 4 hours ago) (1 children)

Infrared is the peak of the frequency range emitted by objects that are roughly body temperature—that doesn’t mean it’s the only frequency that makes objects warm.

In fact all light that isn’t perfectly transmitted or reflected makes things warmer.

Yeah I think my microwave has something it wants to say

I would think it would depend on whether the material the light hits inside the window reflects UV light, or absorbs it and re-emits it as heat.

[–] [email protected] 5 points 5 hours ago (2 children)

Even if it reemits heat, some will be lost to air via convection and half goes wrong way

[–] [email protected] 2 points 3 hours ago

Less than half, because glass isn't a great heat conductor.

[–] [email protected] 2 points 5 hours ago

That’s true of any material that gets warmed by sunlight, though.
