    Why is it that in a mirror that my image is flipped

    i was wondering why is it that in a mirror that my image is fliped but not upside down, why is it in just one plane.

    What is the method for determining the oxidation number of transition elements?

    by organic molecules, did you meen hydrocarbons (alkenes/alkanes...), or things like CO2 , because that's an organic molecule

    Solving for Wavelength of a Surface Water Wave

    I see, well that’s essentially what I was wondering, how can you measure its wavelength, if it was only one continuous wave? -can this be found using the function A*sin(k*x-c*t) if so let me just clarify the terms, is it amplitude, K(1/wavelength), wavenumber(assuming this is one), and phase...

    What are you favorite to hated topics in Physics?

    I beg to differ ?? That is the BEST part of mechanics.. makeing stupid diagrams and having what little 'fun' this topic of physics offers.. my fav was my 1st lesson of a-level physics determining if homer was going to make the jump across the vally on bart's skateboard.. [see pic] o {}...

    Solving for Wavelength of a Surface Water Wave

    If you have a surface water wave (shallow) with equation c = sqrt((gλ / 2 pi) * tanh (2 pi d / λ)) I was wondering how one would go about determining the wavelength. I though it was one continuous wave. Say the wave tank it was in was 60cm long, but it was reflected once (traveled 1.2m). Would...

    What is the method for determining the oxidation number of transition elements?

    transition metals have variable oxidation states, ie Cu +2 and 3+ etc, that whole point of transion metals is that they can have variable oxiadation states (because of the d orbital) any way, other wise most elements have fixed oxidation numbers, Oxygen is -2 becuase it is in group 6. as a...

    Understanding Acid Strength: HSO3- vs H2SO3

    I think some one already said this but i'll say it again. By 'Strength' I am assuming you mean ph, which is the concentration of H+ ions, therefore if an acid can easily disassociate completely more H+ ions are Formed. ie X-H -> X- + H+, but if the acid only partially disassociates not as many...

    Help with determining a wavelength

    ok, I am doing an experiment where i measure the speed of a water wave in a wave tank (see pic) and the fourmla i have to calculate the speed needs the wave length, so far i have justassumed that wavelength was the length of the tank, and that give good results which correspond to some results i...

    Exploring Shallow Water Waves: A-Level Experimentation

    That makes 2 of us, but thanks for all your help. I found a really good site that has lost of useful http://intra.es.lancs.ac.uk:8080/gs/GEPH323/CW98/O_Barton/wave.htm now all i have to do is to write up my coursework! Thanks again, Deimos

    Exploring Shallow Water Waves: A-Level Experimentation

    Hey, I need some help with finding information about shallow water waves. I am doing an A-level (i think that college level.. well its just below degree level) experiment compairing the velocity of a wave with its depth, and need some help finding background scientific information. Everything...
