Thanks Ill check that out

Hello guys, I need to understand the ARCH and GARCH models and so I need some advice on where I should begin my study. In order to understand ARCH models, am I right to begin with studying autoregression? If so can you guys provide me with a link or book I should look into... By the way, I...

I used yellow, turquoise, green, blue, violet. it isn't ment to generate a straight line, for each frequency, the photocurrent (yaxis) is kind of meant to drop like a 1/x graph when plotted against the potential across the xaxis

anode voltage was increased negatively so electron should be repelled from anode in theory, but for some reason i still was obtaining positive photocurrent, maybe i should have taken much larger negative values for potential, so current would eventually become zero?, however do you think i can...

Homework Statement Does the photocurrent drop to zero when a potential across it is equal to the kinetic energy of electrons?, because i found this not to be the case, the photocurrent reached a steady value that didnt decrease further, as i increased the potential across the anode and...

Does the photocurrent drop to zero when a potential across it is equal to the kinetic energy of electrons?, because i found this not to be the case, the photocurrent reached a steady value that didnt decrease further, as i increased the potential across the anode and cathode..

huh? all I am saying is that i plotted average stopping potential on y-axis and frequency on x-axis, and all i want to know is that would my line of best fit go through (0,0) or not.

i have the equation e(electron charge) x V(stopping potential)= h(plancks constant) x f(frequency)

Homework Statement Hello, i was doing an experiment in which you shine different colours of light onto a cathode and apply negative voltage to the anode so that the photo current reduced to a constant value. I obtained the average stopping potential for each wavelength of light (green...
