2021 VCAA Physics Exam Solutions – PDF 100 KB

Thanks to Brendon Beard from Kerang Technical High School for pointing out the following: In Q13 of multiple choice section A, the wave speed is 18 m/s, but the measurements on the wave graph are in cm.  So that makes the wavelength 0.06 and not 6. Frequency is therefore 18/0.06 or 300Hz.  The answer should be C.
