##a^2+b^2\neq 0## isn't this assuming that ##a## and ##b## are purely real which isn't implied in the question?

##y = x +\ln{y}## ##y-\ln{y} = x## ##\frac{dx}{dy} = 1-\frac{1}{y}## ##\frac{dx}{dy} = \frac{y-1}{y}## ##\frac{dy}{dx} = \frac{y}{y-1}## ##\frac{dy}{dx} = 1+ \frac{1}{y-1}## 2nd part ##\frac{dx}{dy} = 1-\frac{1}{y}## ##\frac{d^2x}{dy^2} = \frac{1}{y^2}## ##\frac{d^2y}{dx^2} = y^2##

Hi thereLet’s consider a photon of wavelength λ is being reflected across of gap d meters. The photon is a reflected back and forth between the same points on two horizontal sheets that reflect 100% of the light. What happens when the distance is smaller than wavelength? Thanks

Can someone tell or lead me to how we derive this forumla I=nqAv for current?

Hello Everbody In Sci Shows newest video they take about alternates to Dark Matter and one of these is Modified Newtonian dynamicse. The guy states that there were two teams one proved that it existed and the other did the the opposite. My question is why they can't and didn't compare there...

I can see. I just didnt know whether you did an you were stuck. Good Job E

Have you done the question?

About to go into year 11 and doing physics anything I should do to be ready and get an edge?

@sophiecentaur Thanks for your help. Firstly this a do at home experiment with our 3 week holiday coming up and I am also in Australia which I believe is differernt to the syllabus in the UK. Plus your second comment about the Critical Angle, I really like it and i might consider it but could...

My teacher told me that it wasn't really an experiment and that I was proving a the theroy and that I needed first hand evidence but he said this one was better.

I Its the same one :). The post which you mention my teacher told was really difficult and somethings didn't apply for the requirements. so this is the new one.

Thanks for the help

Hi Everybody I am doing an experiment for a school project where I have chosen to see is the index of refraction changes in a body of water when the temperture changes. So I am using the angle of incidence and refraction to measure using snells law. The Problem: Obviously I need a container to...

What would i do next?
