Hey I am about to start a research paper on the physics concepts involved in relation to fibre optic cabling and copper cabling. In my report I have to discuss how the physics in both relate and differ from one another. In terms of fibre optic cabling I have decided to talk about snell's law...

I'll research that up. Thanks for the help, I think I might know what to do now :).

To measure ammonium, an ammonium ion selective electrode was used. For phosphate, a colorimeter was used. As far the ratio, I'm assuming that there is something (some element in the water sample) that is causing the phosphate to be smaller than it should be. At least that is what I think. My...

Thanks for the reply. Yeah I understand what you are saying, my teacher told me to look into Le Chatelier's principle. As far as other properties go, I'm not quite sure what you mean. I have obtained other results through testing that might be of benefit. Such as the pH levels, TS (total solids)...

Hey I have a problem on my hands, I'm trying to find the concentration of ammonium phosphate in mol/L. Equation: Excuse the badly written equation, I'm not quite sure on how to use subscrips/arrow signs on here. (NH4)3P04 --------------- 3NH4 + P04 Known Data: Mass of 3NH4 measured with...

Yes that it is. Sorry for the mistake haha, I'm still new to the topic.

Hey I have to find a diagram that shows the difference in wavelength intensity between a blueshift and a redshift. I've searched for a while but all the diagrams I find are pretty awful. If anyone knows any that decent ones would you mind linking it below? All I can find is the colour...

Problem: I've been working on my assignment and the purpose of it is to determine the concentration of a contaminant present in a sample of water. I've discovered the contaminant is ammonium phosphate with the levels of each being 200% higher than normal water. I obtained these results using...

Thanks for the help guys, appreciate it a lot. I'll have a look at all the videos :)

Hey I'm 16 and currently studying my last year of physics in high school. I have to write an extended research task on a topic relating directly or indirectly to astrophysics. I have chosen to do the static universe theory vs the expanding universe theory. I've been researching as of late and...

Just attempted the solution and here it is https://www.physicsforums.com/attachment.php?attachmentid=58830&stc=1&d=1368928386 Is that correct?

Thank you :)

Homework Statement Hey I have a question that I have to do that involves expanding a cubic. It is given in the form y = , once it is found I have to square it and then substitute it into a formula to find the area. All I need help with is the expansion than after that it's quite easy.Homework...

I've research this a little bit. From my understanding it only can determine whether there is sulfate present in the water sample, but not the concentration.

The purpose: Basically I've been given a pre-contaminated sample of water, as well as a post-contaminated sample of water. I have to determine what the water is contaminated with, and the concentration of the contaminants present in the water. My Problem: I have determined one contaminant that...
