| Question | Answer |
| Wave Vocab | Energy - 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 |
| Wave Cycle | |
| Transverse and Longitudinal waves | |
| The Equation | |
| Electromagnetic sectrum | |
| Electromagnetic Spectrum continued . . . | Red, mockeys in vans using x-ray guns Radiowaves, microwaves, infrared, visable light, ultraviolt, x-rays, gamma |
| Radiowaves high wavelength low frequency uses: TV and radio no dangers | Microwaves high wavelength low frequency uses: radar and cooking dangers: can create burns, cataracts and cancer? |
| Infra-red high wavelength low frequency uses: seeing dangers: eye danage from bright lights | ultraviolet low wavelength high frequency uses: discos, tanning salons dangers: skin cancer |
| X-rays low wavelength high frequency uses: medical imagry, security dangers: cancer | Gamma waves low wavelength high frequency uses: cancer treatment, observing the universe dangers: cancer |
| More on the Elctromagnetic spectrum . . . | when the wavelength is high the frequency is low and when the frequncy is high the wavelenth is low. |
