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 |
