In longitudinal waves the vibrations are parallel to the direction of energy transfer 1 of 8 Give examples of longitudinal waves Examples of longitudinal waves are: 1. Sound waves and ultrasound. 2. Shock waves e.g. seismic waves] 3. Slinky spring when you push the end 2 of 8 What is the speed of light? Speed of light = 3x10(8) m/s 3 of 8 What is the symbol for wave length lambda 4 of 8 what does the speed of the wave usually depend on? The speed of a wave is usually independent of the frequency or amplitude of the wave 5 of 8 how do you measure the wave length on a longitudinal wave? Measure the centre of the compression to the next centre of compression 6 of 8 What is a compression? Areas where the particles are closer together 7 of 8 What is a rarefaction? Areas where the particles are further apart 8 of 8
