    ofo... electron's nature was already considered a particle. kay? Then de broglie was thinking about how light which is considered a wave has a particle nature.. so then he thought maybe things like electrons which are considered particles would have a wave nature. And no, the only thing...

    okay first of all.. we study wave-particle duality in our syllabus which is about light. That's it. Just how light acts as a wave and a particle. but.. Experiments with a Crookes tube first demonstrated the particle nature of electrons. And the wave nature of electrons comes from the De...

    OH! its caus half life= 0.693/decay constant!

    that's like the most ridiculous answer I've heard all night.. think of some other reason, half life can be of a millisecond too.

    "Half-lives for various radioisotopes can range from a few microseconds to billions of years."

    half life doesn't have to be long.. some elements have half life of minutes even (If I remember right from the practical.. )

    because the rate of emission of alpha particles= half life.. what's the answer in the mark scheme anyway?

    do I need to know how a nuclear reactor works?

    because that's the only time they've given? I donno.. maybe cause they implied that the alpha decay was only for 40 days?... maybe they are just bad at wording the question. It doesn't matter.. its the only time given so it has to be the half life..

    half life is the time taken for half the atoms to decay, in this case by alpha decay. Half life pltted against time has an exponentioal slope and so seen as constant, which means the time taken for alpha decay is constant.

    I have no idea what you guys are talking about but reading the two comments reminded me of Lenz's law... lenz's law always makes the force the other way round.

    does anyone have notes on the direct sensing, medical imaging and communication systems chapters? ... I'm running low on energy and I can't deal with readin this shit any longer!

    people wth is all this derivation of weird equations in the ideal gases chapter? do I neeed to know them?

    what application stuff?.. so far I've read photoelectric effect and wave particle duality, emission and absorption spectra, temperature change and latent heat
