    Radioactivity and density

    yes I realise dense materials stop or reduce radiation, I was just wondering why 70 grains of salt in the center of saint peters dome would stop much better than 1 grain of salt in the middle of saint peters dome. Atoms are seemingly considered mostly space. Is it a charge? It seems the...

    Radioactivity and density

    What is it about the density of a substance that makes it more resistant to allowing radioactivity to pass through it? Since most of the atom is empty space?

    Simple photon question pt 2

    I'm sorry but this doesn't answer my question very well. Could you explain a bit better? More details?

    Simple photon question pt 2

    But is this property a variable pulsation or a movement side to side through space or both?

    Simple photon question pt 2

    Sorry for my ignorance, but what is h and is time an integral part of f?

    Simple photon question pt 2

    Thank you for showing what is the relationship, but why this relationship?

    Simple photon question pt 2

    What exactly does the wavelength of a photon denote? Vibration, pulsation? Why does the smaller wavelengths connote higher energies? What is it about high energies that causes smaller wavelengths?

    Simple photon question

    If anyone has the time, perhaps one could explain to what these vectors refer? Thank you very much if you take the time to explain this to me.

    Simple photon question

    why is light refereed to as the electromagnetic spectrum when light carries no charge and is unaffected by magnets?

    Planck length

    marcus Thanks for taking so much time to explain things worth thinking about. :)

    Planck length

    curvature Would not a line be curved if it was the shortest distance between two points in a curved space? Why would length have no meaning if a surface must be represented as at least a 2d object?

    Planck length

    :) Sorry, my scientific calculator is kaput and I wouldn't know where to start, but if you want to discuss anything, I would be happy to try to understand you. :)

    Planck length

    What I was referring to is that in some popular science, the planck length is referred to as the smallest measureable distance: that distance below this amount would have no meaning in the classical sense. I was asking as to its relativity to geometry. If the planck length is the smallest...

    Planck length

    Is the planck length a commonly accepted theory or is it controversial in any way?
