ELI5 Why are objects underwater blurry to my camera, but not to the naked eye

I noticed that when trying to photograph stuff just below the surface in both sea water and fresh water, what comes through the lenses are just incredibly blurry and full of color fringing while what i see with my own eyes look perfectly normal aside from the refraction effect. Even when using a super telephoto lens (equivalent to 900mm) I can still make out more detail with my naked eye, so something is going on that I'm not understanding.

eli5: Why are contract roles so popular now in Australia?

Is it just me or are there a lot more contract roles available rather than full time roles??

I'm trying to find another job with higher pay and the stability a full time role provides, but I'm seeing lots of 6 month or 12 month contract roles being advertised. It is also harder for me to get to the interview stage for full time roles.

No idea what's happening, can someone explain this to me?

ELI5: Why does Carbon not form quadruple bonds?

When paired with itself, nitrogen has three bonding pairs and one lone pair, so to covalently bond, it forms a triple bond.

Carbon has no lone pairs and 4 bonding pairs if it were to be covalently bonded to itself. So why does it not form quadruple bonds?

ELI5 why are air vents placed on the walls but not floors?

In places like houses or schools or work you usually see air vents placed on the walls but almost never the floor but why? Due to gravity doesn’t it make sense to also add one to the floor as well? Since air is guaranteed to go down but if there’s not a lot of air flow the walls air vents would get significantly less airflow?

ELI5: Why are there ticket scalpers?

In times when ticket prices are disproportionately high, why can't this be regulated better? Can't the official ticket vendors also create a website, similar to TicketSwap, where tickets can be resold but without allowing the original prices to be increased?

ELI5: What exactly precipitated the Seizure of the Grand Mosque?

I’ve read the Wikipedia page and I’m still not really following.

Could someone explain in simplified terms who/what/when/where/why/how?

Was it simple Sunni vs Shia, or old tribal alliances? I’m just not following. Please help.

ELI5: How does drinking tea or any other liquid help clear your lungs?

I’ve always seen people saying “if you have built up mucus in your lungs then drink this or that” but I never really understood that how can a liquid that goes down your throat help to clean/fix/heal your lungs?

and i’m not only referring to mucus that was just an example

eli5 How is water wasted?

Like when ppl say don't wash your yard or car with a hose. Isn't the extra water or for that matter all water either seeping underground and adding to groundwater table or being evaporated into nature to be recycled? In both cases the water will be filtered enough to be potable....
