2021 CAIE AS & A level May June Physics Paper 12 Q. No. 22 (9702/12/M/J/21) by Sajit Chandra Shakya from Nepal Chapter - WAVES Two particles in a progressive wave are a distance 10 cm apart. The two graphs show the variation with time t of the displacement d of the two particles. What could be represented by the two graphs? A particles in a longitudinal wave with a compression and the nearest rarefaction separated by 10 cm B particles in a longitudinal wave with a compression and the nearest rarefaction separated by 20 cm C particles in a transverse wave with a peak and the nearest trough separated by 20 cm D particles in a transverse wave with two adjacent peaks separated by 10 cm
