A little help with Physics homework?
I have summer homework for my 9th grade Physics class. I did this whole science experiment wrong, and i just tried to redo it. See, what I have to do is pour 300mL of water, vegetable oil, and white vinegar into three glasses, and place a pencil in each glass at the same angle. Then I used a protractor to measure the angle of refraction for each liquid. Do these results appear to be accurate?
water bent --7.5 degrees,
white vinegar --9 degrees
vegetable oil- -14 degrees

Possible, vinger and water have quite close figures. It helps to draw a diagram rather than using your naked eye.
