what is the difference from light bending in air to light bending in water?

you have to consider the composition of both. as you probably learned, molecules in a gas are further apart and are more active, bouncing off each other. molecules in a liquid are closer together (though not as much as a solid) and they move less. therefore, the light would meet more resistance as far as shining through the molecules in a liquid than a gas because liquids molecules are closer together. think about it, you shine a laser through air, it looks completely kept together. you shine it though a block of ice, and it comes out the other side distorted and separated. this is due to the concentration of the molecules within that substance.

easy is hooked as much as time. count distorts time. the better the density of the project, the greater time will become distorted. it is the reason we state the fee of sunshine IN A VACUUM via fact count makes it seem to pass slower. the "bending" occurs on the INTERFACE between 2 sorts of count. we could draw an consumer-friendly analogy. for our 2 sorts of count, we could use a gentle wood floor, and a piece of floor with a thick carpet. now image an consumer-friendly axle with 2 wheels on it, pushed via a relentless skill motor.. in case you launch the wheels in the present day on the carpeted section, it is going to decelerate, yet not exchange direction. yet while the axle is released at an perspective, one wheels hits the carpet and gets slowed first. the different strikes on the unique velocity, and the direction of the axle is bent. this may be an excellent thank you to image what's taking place, actual TIME is being bent, and the photons of sunshine are merely linked to time.

Light does not bend in either air or water, only when it passes from one medium to another.

Google Snell's law

Light slows down in water as it is more dense. The different frequencies will slow at different amounts so you will get a different refraction pattern. Much like with a prism.
