light refraction

Do your science homework, and you'll know!

tryin
well im trying to do it thats why i need a hand

Re: tryin


Well, muffin, you're the person who is doing the physics classes.

1. Try to remember what the teacher said.
2. Another idea is to look in your text book.
3. Type "High school physics refraction" into Google.
4. Think about, or find out, what "refractive index" means.
5. (a) Find out why different materials have different refractive indices.
(b) Ask yourself what happens to oil when you heat it.
6. Imagine you have some oil in a beaker.
7. Think how you might measure the temperature of that oil.
8. Think how you might measure the refractive index of that oil.
9. Think what you would do with those measurements.
10. Imagine that you heated it up a bit.
11. Do (7) and (8) again.
12. Write it all down neatly.
13. Draw a couple of diagrams.
14. There. You've done it! It wasn't so hard, was it?

ok
ok fair enough i agree with what you say altho you can put the oil in a beaker as the light will refract through the glass aswell therefore giving the wrong refraction!

Re: ok


Yup fair enough. Although you could measure the empty beaker first, and subtract maybe?

You could put a drop of oil on a flat surface maybe? Buy a Gardco - Atago RX5000 Digital Refractometer and poke its probe in the oil?
