Okay, I think I understand If you look at it as an equation, it's harder to see, but if you visualize it at as a graph that makes sense to me Thanks for your help!

Yes, I understand that, but how does dividing by zero make it infinity? Doesn't that make a number undefined? I was always taught that means it's unsolvable

I usually upload my equations in a neat screenshot, but I will look at Latex I don't understand why it is infinity. (c)^2/(c)^2 = 1 1 - (c)^2/(c)^2 = 0 squareroot of 0 = 0 so how is that infinity?

Oh! Is that my only mistake with calculations? Thank you so much. Why is KE infinite with velocity = c? Wouldn't that make the denominator 1? I don't understand

Homework Statement a) Calculate the kinetic energy required to accelerate a single proton from a rest position to 0.9999c. The mass of a proton is 1.67*10^-27 kg. b) Find the ratio of the kinetic energy to the energy of a proton at rest. c) Explain why no particle accelerator will ever be able...

oh my goodness I am insane and I have no idea how I missed the solution right in front of my nose. thank you for your reply. I had compared d already. so I had the right answer earlier and for some reason late at night chose to delete it and redo it... I deleted my statement about the L...

Updating my second equation because I realized it was out of order and didn't make sense anyway I still got the same answer though. (n-1/2λ)=d sintheta n Basically I rearranged (n-1/2)λ=dx/L for D, and substituted for d (n-1/2)λ=d sintheta n, then rearranged for x. I got: L(sintheta) = x

Homework Statement Imagine that you are conducting an activity with a laser to create an interference pattern. Use the appropriate equations to predict two ways (other than the way described in the following example) to change the interference pattern in order to have closer fringes. Explain...

Homework Statement Choose a technology such as MP3 players, laser, medical imaging, or another that interests you (Other than the cell phone). Research the internet and find out how it is related to the physics of light and waves. In approximately 100-150 words, write a paragraph explaining the...

But if butane gets a methyl group stemming from its 2nd or 3rd carbon, it's 2-methyl-butane? If it's a side group attached to the end can't it be 1-methyl-butane or does it just become pentane?

Thank you so much for your detailed response. It has clarified a lot for me. I think my course expects me to name them the way I did; I was not aware it was an outdated method... this is for chem 12 in Ontario, Canada. As for bond multiplicity your English is perfect. I have been seeing this...

If the bonds are free to rotate can't it just be a methyl group rotating as well as a carbon atom part of the main chain?

Okay, thank you for the information. I still don't understand what bond multiplicity is a) 1,1,2-tribromo-1-propene so this one is right then? c) 1-fluoro-4-methyl-3-pentanone is this one?

what is bond multiplicity? ethane is longer, but I can't tell if the CH3 is a methyl subgroup or if its part of the main chain because it's placed diagonally in the diagram

Homework Statement See attached file Homework Equations N/A The Attempt at a Solution a) 1,1,2-tribromo-1-propene Now this one I'm not sure about. Is the CH3 a methyl group attached to ethene? How can I consistently tell the main hydrocarbon chain in a diagram like this? b)...
