Pretty easy exam right guys? made a couple of stupid mistakes like 0.66m = half wavelength, and then wrote 1 wave length was 0.33m (retard) and I wrote 1 less A and N for the antinode and node question. Probably also lost some marks on the wordy answers, either way, should hopefully end up in the 90's oor worst case scenarios high 80's. Will be distraught if I dont get 95% UMS, if not 100% UMS :P
