I'm not dodging, I was offline. I'm honestly surprised that you are going backwards now. I figured after some reading you would have realized that water really does refract light and wouldn't be trying to still argue that it doesn't.
The pictures of flashlights don't look distorted because everything is submerged. The rays of light bouncing off the flashlight and enabling you to see and take a picture of it are refracted too, just like the light the flashlight itself is emitting. A picture of a fully submerged pencil will look fine too, but a partially submerged pencil looks broken.
If you don't think that water refracts light, can you explain that picture of a spoon in a plastic cup I posted earlier?



No, you are forced to dodge. Here is a question you are guaranteed to dodge: if light refracts when it hits glass and light refracts when it hits water, why can you make a rainbow using glass but not water? Both are mediums of a density different than air, so both will affect light in a similar way. Why does a glass prism work, but a water one doesn't?


You can eraser that question your self - just make a rainbow which just water and some light indoors - why have you dodged doing this for 7 pages now - but since i know you will just dodge by asking more questions:

I'll try to answer that - because Prisms have a higher refractive index and grant grant a greater dispersion that allow for the diffusion of light into the visible EM spectrum.

me ofc.

I am a NASA and i can confirm this theory!

I'm not making a rainbow indoors with water spray because it's difficult to set up. You need a strong light at the right angle, in an area that's waterproof. I'm happy to talk about theory though, or simple experiments that won't soak my house in water. I'm not asking YOU to reproduce a rainbow indoors inside a reflective skydome, am I?

The refractive index of water saturated with sugar is almost exactly the same as glass. So would sugar water work just fine? Besides, if the refractive index of water is too small to separate white light into a visible rainbow, how exactly does the mirror in water experiment work? The mirror is just reflecting light, where does the rainbow come from?

i always find it amusing, as a physics student, reading other people talking about physics like they understand it so well and know it all.. :) (wasn't targeted at anyone specific, the worst thing you can do is argue with someone so far back in the dunning kreuger effect)

EDIT: i've just skimmed through one of the pages of the argument and would advice everyone to learn what these three words mean: Diffraction, Refraction, Rarefraction. Oh boy, people arguing about a topic without knowing what the words they use mean.. :rofl:

When did diffraction and rarefaction come up? I didn't think I missed any pages.

That is the issue. It didn't come up... when there was a lot of talk about it, or maybe it's been mentioned before but people still don't know which they are talking about and don't even know that they are talking about something different. Lots of words being mixed up and people just throwing them around like a football. But anyway, I'm just a spectator.. I'm not ending this argument, this is really amusing :bouncy:
