As light passes through glass or water, do the high or low frequencies of light interact more in the process of abosorption and reemission and therfore lag behind.

Problem is a physist will give you accurate information but probably a bit more than you can use.
What you seem to be asking is which color will bend more when passing through a glass of water giving you the prisim effect.
Consider what you know. If you pass sunlight from a pin hole which color will be on top. It must bend less.
Red light has a longer wavelength and blue or purple light has a shorter wavelength.
Longer wave length light can dodge around the water molecules easier than the shorter wavelength light. (actually any molecules). The one that bends the most reacts the most.

Boy, you can certainly see where people are pasting in material from the same source!
linlyons had a nice empirical argument; good for her.
Other everyday observations confirm that the higher frequencies are most easily scattered:
THE SKY IS BLUE; SUNSETS ARE RED.
In case you want to argue that that's not necessarily true in glass or water, you can either go to an optics textbook and examine the detailed theory of light refraction and/or dispersion to see the frequency, molecular and density factors involved, or look at the behaviour of light passing through prisms or lenses (which, when you think about it, are just well-ordered collections of bits of prisms).
Most elementary physics or astronomy texts will show you how a simple lens, thicker at the middle, bends violet light to focus closer to the nearest lens face than the red light. That means it's being refracted more --- or, in your terms, "Lagging more." (Refraction occurs because the speed of the particular type of light "inside" the medium of interest "lags" behind the speed outside that medium. The more the "lag in speed," the greater the angle of refraction.) Violet light has a shorter wavelength or higher frequency than red light.
If you don't yourself possess a simple prism, you can drive along almost any road in California's Bay Area and see some idiot ahead who has chosen to dangle one from his/her rear-view mirror mount, to dazzle or blind themselves at critical driving moments. I don't necessarily recommend you attempting to confirm the red/blue dispersion differences at high speeds, however. Perhaps you could amuse yourself with this, nevertheless, in a convenient traffic jam.
Live long and prosper.

Its the high wich interact with the lows formming a middle fequency and Light waves also come in many frequencies. The frequency is the number of waves that pass a point in space during any time interval, usually one second. It is measured in units of cycles (waves) per second, or Hertz (Hz). The frequency of visible light is referred to as color, and ranges from 430 trillion Hz, seen as red, to 750 trillion Hz, seen as violet. Again, the full range of frequencies extends beyond the visible spectrum, from less than one billion Hz, as in radio waves, to greater than 3 billion billion Hz, as in gamma rays.
As noted above, light waves are waves of energy. The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. Thus gamma rays have the most energy, and radio waves have the least. Of visible light, violet has the most energy and red the least.
Light not only vibrates at different frequencies, it also travels at different speeds. Light waves move through a vacuum at their maximum speed, 300,000 kilometers per second or 186,000 miles per second, which makes light the fastest phenomenon in the universe. Light waves slow down when they travel inside substances, such as air, water, glass or a diamond. The way different substances affect the speed at which light travels is key to understanding the bending of light, or refraction.
were doing light reflexion in physics and all i know is this equation (sin i)/(sin r)=(n2)/(n1), srry thats in french lol and i know that the (n) of air is 1.0003 and glass is 1.55

Contact your local rescues... see if you can volunteer to help with fundraiser do that until you are 16 & old enough to volunteer to work with the animals start now contacting local vet offices... ask them if you can come in & speak with the vet as well as the vet techs about vetting careers... let them know your goal is to be a vet & that you want to start now doing the things you need to do to set yourself up...ask them what classes you should take go to as many vet offices as will give you the time to talk with someone... keep a journal of who you talked to & what you learn ask them about shadowing vet techs & kennel workers... they may need you to wait until you are 16, but it is worth asking... offer to help with potty-walking write thank-you letters to anyone who will give you their time build relationships NOW with those vets.... because you will need letters of recommendation.... and those letters can mean the difference between getting in & not getting in to vet school Edit to add: Of course vet school is graduate school.... I wasn't suggesting it isn't... I was suggesting you get in front of people in the profession so you can see what they did to get where they are...
