- 1Wave VocabEnergy - the ability to "do work"
Cmpression - being squashed together
Rarefaction - being spread apart
Frequency - the number of wave passing a point each second
Amplitude - maximum displacement of a point on a way away from it's undisturbed position
Displacement - movement away from a point
Wave speed - the speed at which the energy is transfered through the medium - 2Wave Cycle
- 3Transverse and Longitudinal waves
- 4The Equation
- 5Electromagnetic sectrum
- 6Electromagnetic Spectrum continued . . .Red, mockeys in vans using x-ray guns
Radiowaves, microwaves, infrared, visable light, ultraviolt, x-rays, gamma - 7Radiowaves high wavelength low frequency uses: TV and radio no dangersMicrowaves
high wavelength
low frequency
uses: radar and cooking
dangers: can create burns, cataracts and cancer? - 8Infra-red high wavelength low frequency uses: seeing dangers: eye danage from bright lightsultraviolet
low wavelength
high frequency
uses: discos, tanning salons
dangers: skin cancer - 9X-rays low wavelength high frequency uses: medical imagry, security dangers: cancerGamma waves
low wavelength
high frequency
uses: cancer treatment, observing the universe
dangers: cancer - 10More on the Elctromagnetic spectrum . . .when the wavelength is high the frequency is low and when the frequncy is high the wavelenth is low.
