In the photo electric effect .. when your shinning radiation on a metal's surface. If you increase the intensity you increase the number of electrons getting knocked out, but if you increase the frequency your just increasing the K.E the electrons gain right? So frequency has no effect on the current(number of electrons emitted)?

Yes :)
Malak:
Yeah ur right...
Frequency effects KE
And intensity effects no of electrons emitted (if the frequency is equal to the threshold frequency)
Good Luck Everyone...! :D
MasterMath:
Lets hope its mostly electricity.. i hate waves.. Got no time to study it properly..Shouldnt of done A2 and AS in the same year :'(
Malak:
Lol..Can we just hope its easy? ::) ( I dont like electricity) :D

Not trying to discourage you or freak you out , but my teacher said that a very big portion of the exam questions' in the exam are usually Waves ,so I suggest you do take it seriously :)
