QuestionAnswer
What do waves transfer?Waves transfer energy without transferring matter
What direction do traverse waves move?Up and down
Examples of traverse waves?Electromagnetic waves, siesmic S-waves
What direction do longitudinal waves move?Forward and backwards
What is a traverse wave?Direction of vibration is at right angle to the direction of propagation of the wave's energy. This means the particle move at a right angle
What is a longitudinal waves?Direction of the vibration is parallel to the direction of propagation of the wave's energy. This means the particle move back and forth and as the wave moves foward.
What is compression?Compressions are where the particles are close together. They are regions of high pressure or high density.
What is rarefactions?Rarefactions are where the particles are further apart. They are regions of low pressure or low density.
What is wavelength?The distance between any point on a wave and the equivalent point on the next
What is amplitude?The maximum distance a point moves from it's rest position when a wave passes.
What are wavelength and amplitude measured in?Meters, m
What is frequency measured in?Hertz, Hz
What is time measured in?Seconds, s
What is time period?The time period of a wave is the time taken to complete one oscillation
How to calculate frequency?1/time period
What is the equation for waves?speed of wave = frequency X wavelength
