- waves
- definitions
- wave speed = frequency x wave length
- wave length = distance between one peek to the next
- frequency = how many complete waves in a secon
- amplitude is the height of the wave
- period is the time it takes for one complete wave to pass a point
- types of wave
- transverse waves = the vibrations are 90* to the direction energy is transferred by the wave
- light
- slinky spring wiggled up and down
- ripples in water
- longitudinal waves = the vibrations are along the same direction as the wave transfers energy
- slinky when you push one end
- sound and ultrasound
- shock waves
- transverse waves = the vibrations are 90* to the direction energy is transferred by the wave
- waves transfer energy and information without transferring matter
- frequency = 1 time period or f=1T
- use the above relationships in different contexts including sound waves and electromagnetic waves
- waves are diffracted when they pass an edge and through a gap but this depends on wavelength and pysical dimension of the gap
