Physics Unit 1 - Waves 0.0 / 5 ? PhysicsWavesNational 5All boards Created by: e03Created on: 12-03-19 19:49 What is a transverse wave? In transverse waves the particles vibrate at a right angle to the direction that the energy travels. 1 of 11 What is a Longitudinal wave? The energy travels along in the same direction as the particles vibrate 2 of 11 Examples of Transverse waves Water , light, radio. TV 3 of 11 Example of longitudinal waves Sound and ultrasound 4 of 11 What is diffraction? Diffraction is the bending of waves around an object/ barrier or through a gap 5 of 11 What waves diffract best? The greater the wavelength, the greater the diffraction 6 of 11 What is the order of the EM spectrum from the longest wavelength to the shortest wavelength? Radio waves, TV waves, microwaves, Infrared radiation, Visible light, Ultraviolet radiation, X-Rays, Gamma Rays 7 of 11 What Electromagnetic wave has the longest wavelength? Radio waves 8 of 11 What Electromagnetic wave has the highest frequency? Gamma Rays 9 of 11 Which Electromagnetic wave has the lowest energy? Radio waves 10 of 11 What is Refraction? process where speed and wavelength of a wave changes as it travels from one medium to another 11 of 11
