Wave Basics 0.0 / 5 ? PhysicsParticle physicsASAQA Created by: tahliaDCreated on: 11-10-15 23:21 What is meant by 'progressive' wave? A moving wave 1 of 10 What is its purpose? To carry energy without carrying material 2 of 10 What is the cause of waves? When something cause particles or fields to oscillate at a source 3 of 10 List two ways that we can tell waves carry energy Electromagnetic waves transfer heat to objects, X-ray and Gamma rays cause ionising radiation which can knock electrons out of orbit 4 of 10 What do waves tranfer energy through? Mediums 5 of 10 List another two ways that we can tell waves carry energy Loud noises cause air oscillations which can make things vibrate, Wave power can be used to generate electricity 6 of 10 Name three way in which a wave can be affected Reflection, Diffraction, Refraction 7 of 10 Give a brief definition for Reflection A wave is reflected (or bounces back to the source) at a boundary 8 of 10 Give a brief definition of Diffraction When a wave passes through a gap, causing it to spread out 9 of 10 Give a brief definition of Refraction When a wave changes direction as it enters a different medium 10 of 10
