P1C 0.0 / 5 ? PhysicsWavesGCSEOCR Created by: ellxeCreated on: 01-05-16 05:45 What is amplitude? Displacement from rest position to crest (not trough to crest) 1 of 12 What is the wavelength? Length from crest to crest 2 of 12 What is the frequency? Number of complete cycles or oscillations passing a certain point per second 3 of 12 What is frequency measured in? Hz 4 of 12 Wave speed equation? Wave speed (m/s) = Frequency(Hz) X Wavelength(m) 5 of 12 What is 1 kilohertz(kHz) and 1 megahertz(MHz) in Hz? 1 kHz = 1000 Hz, 1 MHz = 1 000 000 Hz 6 of 12 All waves can be... (r, r, d) Reflected, Refracted, Diffracted 7 of 12 How can we see things? Reflection of light 8 of 12 Law of reflection? Angle of incidence = angle of reflection 9 of 12 What does total internal reflection depend on? The critical angle 10 of 12 What is diffraction? Waves spreading out 11 of 12 What is refraction? Changing the speed of a wave so it can change direction 12 of 12
