Quote from: "maxleng"according to this Q (neap 2006)a larger slit width has a larger pattern, and smaller width has a smaller pattern (note: spacing is still the same) which should give the answer C on our examsry, but the answer for that is wrong, i checked with my tutor a few weeks agon spirited i got the same cept for the 2nd light q, were u meant to get the h value from the graph as well, cos i just used the 6.63E-34..... ooh i think thats y it was 3 marks, was it 3marks?... oh n u have very good memory

2.5 A, 11 V, 2.2 V, 6W, 5.5W, 5.5W
but when you increase gap width, you increase w and thus ratio wavelength/w decreases and there's less diffraction, meaning that it'll bunch up... i dunno. i said C initially but i changed my mind.
AH THAT'S NOT FAIR. NEAP HAD A SIMILAR QUESTION AND THEY USED 2.0 OHMS. FUCK YOU NEAP.
