Look....u measure the distance between 2 compressions and multiply by three quarters....thats wat GG meant ;)....then u measure out that distance from the compression points and just PLOT it :P

Somebody pls help me out with this question.....im totally confused :-\:
Why does the Kinetic E of emitted electrons in the photoelectric effect depend only on the frequency and not on the intensity of the light????
Malak:
^ Because its the frequency of the light that determines the photon energy (E=hf), A brighter light i.e. greater intensity only means that there are more photons present so more electrons can be emitted. It doesnt effect the K.E of the electrons.
More energy means more K.E
