Angle of incidence is equal to the angle of reflection (3, 2, 10) 5. Change in direction of a ray of light passing from one medium to another at an angle (10) 6. Point of 0 amplitude on a standing wave (4) 8. Refers to the position within a cycle that the particle occupies relative to the onset of the cycle (5) 9. Pulses sent into body and bounce back when there is a change in density (tissue); reflections detected; computer generates an image (10) 10. A line joining all points in a medium where the waves are in phase (9) Down 2. Point of maximum amplitude on a standing wave (8) 3. Ratio of the speed in medium 1 to speed in medium 2 (10, 5) 4. Waves which require a medium to travel through (10, 5) 7. Time taken for one complete oscillation to occur, seconds (6, 1)
