Waves 4.5 / 5 based on 3 ratings ? PhysicsWavesASAQA Created by: Alice BayleyCreated on: 29-03-13 12:15 10853967214 Across 1. maximum displacement of a vibrating particle. (measure from middle to maximum positive or maximum negative, not maximum positive to maximum negative) (9) 4. where a trough meets a trough; the two waves reinforce each other. (11) 5. Travel through a substance e.g. sound waves (10, 5) 6. the number of cycles of vibration of a particle per second, or the number of complete waces passing a point per second. Measured in hertz (Hz) (9) 10. waves in which the direction of vibration of the particles is perpendicular to the direction in which the wave travels. (10, 5) Down 2. straight waves directed at a certain angle to a hard, flat surface reflect off at the same angle. (10) 3. when a crest meets a trough, the resultant displacement is zero (12) 7. where a crest meets a crest; the two waves reinforce each otherq (10) 8. the least distance between two adjacent vibrating particles with the same displacement and velocity at the same time. (10) 9. when waves meet, they combine for an instant before moving apart. (13)
