- waves
- transverse waves
- the oscillations are perpendicular to the direction of energy transfer
- microwaves
- light waves
- water waves
- electromagnetic waves
- infrared waves
- radio waves
- Mexican waves haha
- ultraviolet waves
- X-rays
- gamma waves
- longitudinal waves
- the oscillations are parallel to the direction of energy transfer
- sound waves
- seismic waves
- compressions
- a compression is a region where particles of a medium are close together
- rarefactions
- a rarefaction is a reign where particles of the medium are spaced apart
- waves transfer ENERGY from one place to another NOT matter
- this means that energy can be transferred even without matter
- wavelength
- distance from peak to peak or trough to trough of a wavelength
- measured in metres (m)
- frequency
- frequency is the number of wave cycles that pass a point per second
- it is measured in hertz
- can be calculates using the equation: frequency (hZ) = 1/time period (s)
- frequency is the number of wave cycles that pass a point per second
- the electromagn-etic spectrum
- the electromagn-etic spectrum is the family of all different types of light. They are all transverse waves.
- the waves differ because they have different wavelengths and frequencies.
- however, they are all similar because they can all travel through a vacuum and they all travel at the same speed in the vacuum - the speed of light
- the waves differ because they have different wavelengths and frequencies.
- radio waves microwaves infra-red visible light ultra violet x-rays gamma rays
- [R]emember [M]y [I]nstructions [V]isible [U]nder [X]ray [G]lasses
- low frequency + high wavelength
- high frequency + low wavelength
- the electromagn-etic spectrum is the family of all different types of light. They are all transverse waves.
