what does precision actually means? no of sf it can measure to or the least measuremnt the device can measure?
basically the smallest division of an instrument is its precision. Being precise basically means that there's not a large fluctuation between repeating readings.

Has anyone written down the Polarisation of light experiment? Its on Page 101 in the textbook.
it's come up twice. Once in a unit 2 paper, and once in a unit 3 paper

Is the photoelectric effect, poiseuillie's experiment or the young modulus exp more likely to come- what do u guys think?

im thinking photoelectric emssion for the experiment question and for the graph idk :/ what is poiseuillie's experiment?

Guys can an oscilloscope measure frequency if not how can we measure frequency?

unit 3, jan 13 last question
unit 2, june 2011 ex 16 bii
dude if we use v=(h/e)f-workfunction/e Graph the y intercept multiplied by E gives a negative value of workfunction so we have to multiply it by -1 to make it positive ?
and one more thing can we measure frequency using oscilliscope if not what device shall we use?

yeah the modulus of the y-intercept is workfuction/e

the frequency of what? you can measure the frequency of sound with a microscope connected to a cathode ray oscilloscope with the time base on, or the frequency of microwaves with a receiving aerial with a cro, you can't do that with visible light tho

its the negative value of workfunction/e since its -workfunction/e right?
