ND Physics Revision 0.0 / 5 ? PhysicsWavesGCSENone Created by: martyna.klCreated on: 28-11-17 19:01 What is a wave? A regular vibration that carries energy. 1 of 10 What is the riddle for all the waves? Real / Men / Ignore / Very / Ugly / Ex / Girlfriends - Radio Waves / Microwaves / Infra-Red Waves / Visible Light / UltraViolet Waves / X-Rays / Gamma Rays 2 of 10 What are the properties of a gamma ray? Shortest Wavelength , Highest Frequency 3 of 10 How do you calculate the FREQUENCY of a wave? Frequency (HERTZ) = 1 / Time (S) 4 of 10 How do you calculate the SPEED of a wave? Speed ( M/S ) = Frequency (HERTZ) X Wavelength (METRES) 5 of 10 What is the distance between each peak of the wave called? The wavelength. 6 of 10 What is the 'reflection of a wave'? It is when a wave bounces off the surface of an obstacle. 7 of 10 What is the 'refraction of a wave'? Refraction occurs when a wave moves from one material to another. 8 of 10 What is changed during 'refraction'? The speed and wavelength are changed. (The frequency and period stay the same) 9 of 10 What is the 'diffraction of a wave'? Diffraction occurs when a wave passes an edge / goes through a small gap / goes past an object. 10 of 10
