thnku @ captain .... now could any one plz tell ?

a)i) diffraction, reflection, refraction
ii) photoelectric effect

b)ii) minimum wavelength means maximum energy gap ... max energy gap is from 0.87 to 5.44...

E = hc/λ is the formula to use...
for lines see the diagram...

FOR PHYSICS ASLEVEL PAPER 33

what we hav been practicing is the electricity one with beads in place of resistors.its very simple..and ya in the oscillation one we will be having a cylinder instead of a pendulam bob..

i doubt anything concerning magnets or diodes on A2 level will come for As practicals, hmm, they might just be giving diode as just another component of the circuit system, in past years there were things like that, but the procedure is still the same, you will just have to either measure current, volt etc. and draw the graph, and by the way it will be helpful to review the graphs for diodes. before going for exam.

YOU WILL NEED
1.retort stand.
2.bob/cylinder
3.stopwatch.
4.thread
5.multimeters
6.batteries
7.clamps.
8.resistors.
